PREBEAMST
Pre-Processing for Code Checking using BEAMST


1.       Introduction


1.1. General Description

PREBEAMST is a pre-processor for BEAMST, the code checking module of the ASAS Offshore suite which
computes member stresses and undertakes member strength and joint punching shear checks to a variety of
codes of practice. The nature of the code checks requires that additional parameter information is supplied to
supplement that which is obtained from the analysis structural model. Typical parameters are the yield stress,
unbraced lengths, effective length factors, moment amplification reduction factors, etc.                     To assist in the
development of a suitable input file for BEAMST, the PREBEAMST program generates a fully annotated data
file from a reduced input data description and a suitable ASAS backing file. The generated data file can
subsequently be modified, if required, prior to being used as input to BEAMST.

The pre-processor incorporates the following facilities

     •       Automatic retrieval of the loadcase numbers analysed on the ASAS backing files

     •       Selective processing of individual elements or joints using element, group or joint data

     •       Design override capability to allow user defined joint configuration and secondary member definition

     •       Explicit definition of unbraced lengths, effective lengths, and yield values for each element or group

     •       Explicit definition of the pure bending coefficient and the moment amplification reduction factor for
             each element or group

     •       Computation of unbraced lengths for elements constituting a contiguous member

     •       Yield values may be computed from thickness dependent yield tables

     •       Provision for defining the Ultimate Tensile Strength for punching shear checks

2.     Facilities in PREBEAMST


2.1. Element and Joint Selection

PREBEAMST allows selective processing of one or more individual elements or joints in the model, depending
upon the code check required. This allows BEAMST data files to be generated for specific areas of a model and
examining the effect of local parameter changes.

For member code checks, elements may be referenced directly or collectively using their group number(s).
Alternatively the keyword ALL may be utilised to request that every tube or beam element in the analysis is to
be processed.

Joint checks are referenced by the user node number or by using the keyword ALL to request that every joint
which has valid elements connected is processed.


2.2. Load Definitions

Both member strength and joint punching shear checks require information about the loadcases that are to be
processed. PREBEAMST interrogates the ASAS backing files relating to the model and extracts the loadcase
numbers that have been analysed and transfers them to the output data file.


2.3. Yield Values

Yield stress values are required for determining the allowable stresses in member utilisation checks. Yield
values may be supplied either explicitly, on an element or group basis, or by defining a steel grade
yield/thickness table which allows the program to compute the required yield value based upon the material
thickness. For stepped beams with different thicknesses yield values will be generated for each step.

Yield tables are named so that more than one may be defined, thus allowing different grades of steel to be
modelled in one PREBEAMST process. Up to five yield values may be supplied within each table.

For joint punching shear checks the API code of practice requires that the lesser of the yield stress or 2/3 of the
ultimate tensile strength is used for computing the allowable stresses. The UTS value may be supplied either
explicitly for the chord elements concerned, or by reference to a user defined steel grade UTS value.


2.4. Parameter Information

In order to undertake member strength and punching shear code checks it is required to define additional
information relating to the following parameters

    PREBEAMST User Manual                                                                               Facilities in PREBEAMST


   •        The pure bending coefficient, Cb, used in determining the allowable major axis pure bending
            allowable stress. This value can either be directly supplied by the user, or may be computed within
            BEAMST based upon the moment distribution along the element. The latter can be requested by
            selecting the AUTO option on the CB command.

   •        The moment amplification reduction factors, Cmy and Cmz, used in the combined axial and bending
            buckle unity check. These values can either be directly supplied by the user, or may be computed
            within BEAMST based upon the moment distribution along the element. The latter can be requested
            by selecting the AUTO option on the CMY/Z commands. If MEMBers have been defined (see
            below) CMY and/or CMZ default to 0.85 for constituent element. See Section 2.5 Members below
            for further details.

   •        The unbraced length which is used in computing the slenderness ratios for column buckling
            calculations about each of the element lateral axes. By default PREBEAMST will compute a length
            based upon the nodal length of the element, modified to account for offsets where defined. If required
            explicit values of the unbraced length of an element may be provided, either as an absolute length or
            as a factor of the actual length (including offsets). If MEMBers have been defined (see below) the
            unbraced length is computed from the start and end coordinates of the member, again modified to
            account for any defined offsets at either end. This member length will be applied as the unbraced
            length to each of the constituent members. This unbraced length will not be modified by any element
            unbraced length definition.

   •        The effective length factor, K, is used, together with the unbraced length, in calculating the element
            slenderness ratio for column buckling calculations about each lateral axis. By default, an effective
            length factor of 1.0 is adopted, but this may be overridden for each axis for specific elements or
            groups.



2.5. Members

There are many instances when physical members are modelled analytically using two or more structural
elements, for example, where lateral members are connected or at appurtenances. In such situations, the
unbraced length of the constituent elements should reflect the total length of the member and not just the
individual elements themselves. To assist the user in determining the appropriate unbraced length, member
strings may be defined which are then used by PREBEAMST in computing the required length. Member
definitions may be provided for single or biaxial conditions thus permitting the modelling of intermediate lateral
restraint about one axis.

                                                  Figure 1 Member Definitions

For the example shown in Figure 1, the local Y direction elements 1 and 2 may be considered as one member,
whilst in the local Z direction the member consists of all 3 elements. Note that there is an implicit assumption
that the local axes of all elements in a member are consistent.


2.6. Joint Types

By default, PREBEAMST in common with BEAMST, utilises the geometric and topology information that is
stored in the ASAS structural model backing files.                       This information is used in determining the joint
configuration in the joint punching shear checks.

There may be instances when the data utilised in the structural analysis is inconsistent with that required to
undertake the joint check and PREBEAMST provides several mechanisms to override the value that would be
adopted by default.

1.      Chord selection at a joint is normally based upon searching for the largest diameter connecting elements.
        Where several members have the same diameter, the elements with the largest thickness are adopted. In
        certain circumstances this methodology cannot determine a unique chord member.                            PREBEAMST
        enables the user to predefine the chord member(s) if required.

2.     Joint configuration in BEAMST is identified by investigating the topology of the brace members incident
       at that joint.

There may be situations when a joint type other than that computed by the program is required. PREBEAMST
provides a joint type specification (the TYPE command) which will override the computed configuration. Since
the configurations are load dependent, different joint types may be specified for a brace for different loadcases.
As required by the API code up to two different classifications may be assigned to a brace for a given loadcase
(with associated percentages for undertaking the interpolation function).

2.8. Exclusions

The commands utilised in PREBEAMST are a modified subset of the full BEAMST data set, with the addition
of the member steel grade and UTS commands. Since PREBEAMST is intended to be used to generate a file
which can be modified prior to submission to BEAMST only those commands contained within this manual will
be recognised, the remaining BEAMST commands not listed herein will be rejected by the program and must be
added as necessary by the user prior to running BEAMST. The following is a list of BEAMST data commands
that will not be accepted by PREBEAMST.

2.9. UNITS

If UNITS have been employed in the ASAS analysis it is possible to specify modified units for the input data to
PREBEAMST.




Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.              Page 2-6
    PREBEAMST User Manual                                                                               Facilities in PREBEAMST


If local modified input data units are required, this is achieved by specifying one or more UNITS commands
within the main body of the PREBEAMST data thus permitting a combination of unit systems within the one
data file (see UNITS command, Section 3.3).

If UNITS were not employed in the ASAS analysis, the UNITS command may still be specified to modify the
input data units provided a UNITS command is defined in the Preliminary Data specifying the consistent units
employed in the previous structural analysis. See Section A.12 for further details.

It is suggested that units are utilised since much of the data generated is unit dependent and may not be definable
without a units definition.


2.10. Output data file

PREBEAMST produces a generated data file which, assuming no errors have been detected and any required
data items listed in Section 2.8 above have been included, may be submitted directly to BEAMST for processing.
One of the advantages of PREBEAMST, however, is the provision of a readable text file which may be modified
and extended as required. Thus PREBEAMST should be seen as providing a first pass data file which can be
subsequently adapted to meet the changing requirements of the fatigue analysis.

To assist the user in modifying the resulting data file, extensive annotation is provided by way of commentary
giving information as to the derivation of generated data.                      This facility provides an immediate check on
methodologies adopted for parameter generation and is of a form that can be readily updated, by the user, to be
consistent with the data attached. An example of a resulting data file is shown in Figure 2.1below.

3.       Input Data

As with other programs of the ASAS suite, the input of information and data is divided into two sections. The
first is the Preliminary Data followed by the main PREBEAMST Command Data Block.

The Preliminary Data defines the relationship of the run to all the other runs already completed in the project, the
backing files required and also specifies the title of the run. The full details of these commands, along with
examples, are given in Appendix -A of this manual.

The available commands for each type of code check are summarised in Tables 3.1 and 3.2.                   Detailed
descriptions of each of the commands will be found in the remainder of Chapter 3


3.1. Command Structures



3.1.1.      Command Syntax

The input data for PREBEAMST are specified according to syntax diagrams similar to the one shown below.
The conventions adopted are described in the following paragraphs.
                                   item
              KEYWORD
                                              KEY               real




Within a data block, each horizontal branch represents a possible input instruction. Input instructions are
composed of keywords (shown in UPPER-CASE), numerical values or alphanumerics (shown in lower-case
characters) and special symbols. Each item in the list is separated from each other by a comma or one or more
blank spaces.

A data list is indicated by a horizontal arrow around the list variable
                list




Optional data items are indicated by an arrow which bypasses the item(s)
                 item




Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.   Page 3-1
      PREBEAMST User Manual                                                                              Input Data


Alternatively, where optional items are part of a list of values they may be represented by enclosing brackets.

                value1               (value2... value n)




Where one or more possible alternative items may appear in the line, these are shown be separate branches for
each. These branches may rejoin further along the command if appropriate.

                    KEYWORD1


                    KEYWORD2




An input line must not be longer than 80 characters.




3.1.2.        Data Types

Data is entered in three forms:

(a)      Integer Number


If an integer number is required a decimal point must not be supplied. When a list of integer numbers is
required, the following abbreviations may be used:

       (i)      Where the integer list represents all items from an existing list (for example, choosing all groups
                for processing) the list may be replaced by the word ALL. For example

                                       GROU ALL               generates all possible groups.

       (ii)     A sequence of integers may be generated by giving the first and last values separated by the
                keyword TO. For example 5 TO 8 generates the numbers 5,6,7 and 8.

(b)      Real Number


If a real number is required the decimal point may be omitted if the value is a whole number. Exponent formats
may be utilised when real numbers are required. For example

                         0.004         4.0E-3 4.0D-3 are equivalent
similarly                410.0         410          4.10E2 have the same value

(c)      Alphanumeric

    PREBEAMST User Manual                                                                                               Input Data


Alphanumeric data is used for keywords and text strings. The data must begin with a non-numeric character.
The letters A-Z may be supplied in either upper or lower case but no distinction is made between the upper and
lower case form. Hence “A” is assumed identical with “a”, “B” with “b” and so on. For example

                         COMB                   Comb               comb            are all identical strings.




3.1.3.      Special Symbols

The following is a list of characters which have a special significance to the PREBEAMST input.



*        An asterisk is used to define the beginning of a comment, whatever follows on the line will not be
         interpreted. It may appear anywhere on the line, any preceding data will be processed as normal. For
         example

                              * THIS IS A COMMENT FOR THE WHOLE LINE
                              CASE 4 2.7 * THIS IS A COMMENT FOR PART OF A LINE




,        A comma or one or more consecutive blanks will act as a delimiter between items in the line.

         For example              5, 10, 15                                is the same as           5   10      15




         Note that two commas together signify that an item has been omitted. This may be permissible for
         certain data blocks.

         For example              5,, 15                                  is the same as            5   0    15

         Unless otherwise stated in the section describing the data block, omitted numerical values are zero.


3.2. Priority of Data Assignments

There are a number of commands that allow element and element ‘step’ data to be assigned in terms of element,
group or property numbers. These appear in the command syntax diagrams in the following format:

                                                                               ELEM
      COMMand                      STEP          integer                                                integer list
                                                                               GROU



The priority of such assignments is defined below.




Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.                  Page 3-3
    PREBEAMST User Manual                                                                                Input Data


Element data        -    use element data assigned to individual elements (ELEM)
       if none      -    use element data assigned to the group the element belongs to (GROU)
       if none      -    no element data assigned to element.

Step data           -    use step data assigned to individual elements (ELEM)
       if none      -    use step data assigned to the group the element belongs to (GROU)
       if none      -    use element data assigned to individual elements (ELEM)
       if none      -    use element data assigned to the group the element belongs to (GROU)
       if none      -    no step data assigned to element.

Element and step data assignment is not order dependant. This is demonstrated by the following example:

                 COMMand .... data1 ELEM 1
                 COMMand .... data2 GROU 5
                 COMMand .... data3 ELEM 2

Assuming elements 1 and 2 are in group 5:

       Element 1 has data1 assigned

       Element 2 has data3 assigned

       All other elements in group 5 have data 2 assigned


It should be noted that when step data is explicitly being defined it overrides any element assignments even if the
step data is assigned to a group and the element data assigned to an individual element. Thus in the following
example:

                 COMMand .... data1 STEP 2 GROU 5
                 COMMand .... data3 ELEM 1
                 COMMand .... data4 STEP 2 ELEM 2

Step 2 of element 1 has data1 assigned as part of the group 5 definition. In this instance the step specific group
assignment overrides the element assignment which is not step specific.

       Step 2 of element 2 has data4 assigned.

       Step 2 of all other elements in group 5 have data1 assigned.

       All steps, except step 2, of element 1 have data3 assigned.

       No data is assigned to any steps, other than step 2, for any elements other than element 1.



3.3. Units Command

Specifies the units associated with subsequent data or the units to be used for stress and force reporting in the
subsequent BEAMST analysis. This command may be specified only once if analysis units have not been
defined (see Section 2.9) in order to define BEAMST output units.




Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.   Page 3-4
     PREBEAMST User Manual                                                                               Input Data




Parameters
UNITS         : keyword

STRE          : keyword denoting that the output stress units for BEAMST are to be defined

unitnm        : Name of unit to be utilised (see below)

Notes


1.      Force and length units may be specified. Only those terms which are required to be modified need to be
        specified, undefined terms will default to those of the analysis global units unless previously overwritten
        by another UNITS command. If analysis units are not operational both force and length must be defined.

2.      Valid unit names are as follows

        Length                    METRE(S)                            M
                                  CENTIMETRE(S)                       CM

3.     Provided UNITS were utilised in the preceding ASAS analysis, the UNITS command may be repeated
       throughout the data file thus permitting the greatest flexibility in data input. If UNITS were not employed
       in the ASAS run, only one UNITS definition may be supplied giving the force or stress units for
       BEAMST.

4.     Output stress and force units will be output as modified PRIN commands in the BEAMST input data file.
       The default units for forces are those used for the analysis. The default units for stresses are N and mm.

3.4. PREBEAMST Command Sets

PREBEAMST data consists of a command set according to the requirements of the code check to be undertaken.
The command set consists of a header command for the code check, the commands applicable to the check and
an END command to terminate the set.

The structure of a typical PREBEAMST datafile is shown below:

        STOP                                       PREBEAMST datafile terminator




The header command for the command set consists of a keyword defining the design code (currently only API is
supported) and a second keyword (or sub-header) defining the particular requirements from the code, either
member or punching shear checks.                   The PREBEAMST commands relevant to each command set are
summarised in the tables below.

uts               : ultimate tensile strength. (Real)

Usage

At least one GRAD or YIELD command set must be present in member checks. At least one GRAD or UTS
command set must be present in punching shear checks.

Notes


1.      Up to 5 values of yield stress and four values of thickness may be defined for a given grade of steel. It is
        not necessary to use all the table values but there should be one more yield stress value than thickness.

2.      The yield stress value is calculated from the table as follows:

        If

                        t <= th1        then yield = fy1
                th1< t <= th2           then yield = fy2

                th2< t <= th3           then yield = fy3
                th3< t <= th4           then yield = fy4
                th4< t                  then yield = fy5

3.     For stepped beams with different thicknesses, yield values will be generated for each step.

4.     Elements with non-tubular sections can only reference a grade table if the sectional properties have been
       defined in the ASAS analysis, either using an external library file, or using the SECT command. The
       thickest plate section will be used in determining the yield value.

3.13. GROU Command

The GROU command is used to select which ASAS groups are to be processed. This command can be repeated
as many times as required. It is sometimes convenient to select elements by their group numbers and then to
extend the selection with discrete elements or ranges of elements. The ELEM command may be used in
conjunction with the GROU command for this purpose.

     GROU                integer list




Parameters

GROU              : keyword

integer list      : list of ASAS group numbers. (Integer)

3.15. MEMB Command

The MEMB command is used for calculating the unbraced member length of a member which comprises one or
more elements. The idealisation for analysis may have split physical members into several elements. This
command allows the automatic calculation of member properties for use as appropriate.


                               Y
      MEMB                                         integer list
                               Z




Parameters

MEMB              : keyword

Y/Z               : keyword denoting which local axis is being defined

integer list      : list of user element numbers to define a single member. The elements must be specified in a
                     contiguous manner. (Integer)

Usage


Optional. Applicable to API ALLO command data block only.

Notes


1.      The member definition may be for one axis only if either Y or Z is specified. If not specified the member
        definition will apply to both local axes.

2.      Each of the constituent elements in a member must have the same local axis definitions and must be
        colinear.

3.      The member length will be assigned as an unbraced length to each of the constituent elements in the
        appropriate local axes. This member length will not be modified by any UNBR command which may
        reference any of the consistent elements.

4.      The moment amplification reduction factor will be set to 0.85 for the constituent elements about the
        appropriate axes.

Examples


        MEMBER Y 25             29      35
        MEMBER Z 101              TO     104


3.16. SECO Command

The SECO command is used to specify that certain elements defined by their element or group numbers are to
be classed as secondary members and thus excluded from joint punching shear checks.
                             ELEM

Usage


Optional for joint punching shear and brace end fatigue command data block.

Notes


1.       In the absence of any TYPE command(s) at a joint, joints will automatically be classified as K, T, Y or X
         depending upon each brace-chord pair geometry.

     •      For single brace members the joint is designated as a T if the angle subtended with the chord is 90° ±
            5°. Otherwise the joint is classified as a Y.

     •      For two brace members in the same plane the joint is classified as an X. If the braces are on the same
            side of the chord the joint is designated as a K joint.

     •      In all other instances the braces are designated as Y or T.


2.       If percentage is omitted, the joint is classified as 100% joint type. If percentage is less than 100,
         type2 must be present.

3.       All joint types not specified with the TYPE command will be automatically classified as above.

4.       If the gap dimension is omitted a default gap of 75mm is assumed provided units are operational.

5.       All required user loadcase numbers must be supplied if the CASE keyword is employed, the shorthand
         syntax ALL is permissible. If the CASE keyword is omitted then all loadcases are assumed and should
         not be specified.

3.18. UNBR Command

                                                       ℓy
The UNBR command is used to specify the unbraced lengths and ℓz used in calculating slenderness ratios
Kℓ/r for column buckling calculations about each axis. With this command either unbraced lengths can be
specified or factors by which the actual element length must be multiplied.
                          Y                  FACT         factor                                  ELEM

integer list       : list of user element numbers or element group numbers. (Integer)

Usage


Optional. Applicable to API ALLO command data block only.

Notes


1.      If neither LENG nor FACT is specified, then LENG is assumed by default.

2.      If the Y or Z local axis is not specified, ℓ y and ℓz are both set.

3.      If the UNBR command is omitted, the unbraced length is assumed equal to the element length. If
        members have been defined then the total accumulated member length is assigned to each constituent
        element.

Examples


        UNBR 22.O           15.O        ELEM       1O1      1O6       112

3.19. UTS Command

The UTS command is used to specify the ultimate tensile strength (UTS) to be used for a chord element in a
punch shear check. This UTS value may be assigned to a particular step number within the elements defined by
the element or group lists. The command may reference a steel grade if defined using the GRAD command.
                   v alue                                        ELEM

Parameters

UTS                : keyword

value              : the yield stress. (Real)

grade              : steel grade name defined using a GRADE command. (Alphanumeric, 8 characters)

STEP               : keyword to denote that step number follows

stepno             : step number to which the yield stress is referenced. (Integer)

integer list      : list of user element, group or material property numbers to be assigned this yield stress.
                     (Integer)

Usage

Compulsory (but see note 4 below). Applicable to API PUNC command data block only. A value of 2/3 of the
UTS will be generated for chord members as required for the punching shear checks. For the joint strength
computation, brace yield values are also required so YIELd definitions should also be provided.

Notes

1.      Element definition of UTS overrides group definition. If an element has a UTS referenced to a STEP
        number, this will override any value specified by element or group as a whole. If the STEP referenced
        UTS is specified the element defined value will override the group definition.

2.      The UTS value must be entered in the same units as defined by the UNIT command.

3.      If a step reference is given, only that step for elements specified within the element list or group number
        list are assigned this yield stress.

4.      If UTS values are not supplied the program will utilise yield values, if defined.

5.      If an unstepped element is both a chord and a brace then the minimum of 2/3 UTS and the yield value
        will be adopted.

Examples


        UTS      2.OE8        ELEM       ALL

3.20. YIEL Command

The YIEL command is used to specify the yield stress to be used for an element or group to be processed. This
yield stress may be assigned to a particular step number within the elements defined by the element or group
lists. The command may reference a steel grade if defined using the GRAD command.

grade             : steel grade name defined using a GRADE command. (Alphanumeric, 8 characters)

STEP              : keyword to denote that step number follows

stepno            : step number to which the yield stress is referenced. (Integer)

ELEM              : keyword to denote that element numbers follow

GROU              : keyword to denote that group numbers follow

integer list      : list of user element, group or material property numbers to be assigned this yield stress.
                     (Integer)
Usage


Compulsory. For all stress checks to design code command data blocks.

Notes


1.      Element definition of yield stress overrides group definition. If an element has a yield stress referenced to
        a STEP number, this will override any value specified by element or group as a whole. If the STEP
        referenced yield stress is specified, the element defined value will override the group definition.

2.      The yield stress value must be entered in the same units as defined by the UNIT command.

3.      If a step reference is given only that step for elements specified within the element list or group number
        list are assigned this yield stress.

A.1         Introduction
The preliminary data is the first block of the PREBEAMST data. It defines the memory size to be used, the
project name, structure and component names and file names to be used. Any options specified or save
commands used will be ignored for the purposes of PREBEAMST but may be included for the subsequent
BEAMST analysis. All commands and comments in the Preliminary data will be copied verbatum to the
resulting data file.

                              Appendix - B                   - Running PREBEAMST


B.1         ASAS Files Required by PREBEAMST
PREBEAMST operates on the files produced by a preceding ASAS, LOCO or RESPONSE analysis and hence
these files must physically be present in the user’s disc space for the program to run successfully. In all cases the
project file must exist which contains information about all other files in the current set of analyses. The name
of this file is derived from the four character Project Name defined on all the PROJECT commands in the set.
(For example, if the Project Name is PRKZ, then the Project File will be PRKZ1O).

For the ASAS analysis preceding this run, with a ‘SAVE LOCO FILES’ command in its preliminary data block,
there will be a physical file containing the model data and forces and moments from that analysis. Again the
physical file name is derived from the four character name defined on the FILES command. Typically, if the
name used was JACK then the physical file will be JACK35. The forces and moments may relate to the analysis
of a structure or to the results associated with the elements at any level in a substructured analysis. Provided that
the user has the requisite files on disc the program will handle them in a transparent manner.

The preceding analysis must have run to completion. If the run did not complete either because of a failure or
because the user terminated the run deliberately with a RESTART command, PREBEAMST may error because
some files may not exist.


B.3         Running Instructions for PREBEAMST
See the appendices in the ASAS User Manual, Volume 1, for details on how to run any of the programs in the
ASAS suite.



B.3         Output File
Two files will be written to during a PREBEAMST run. The standard listing file will contain a data echo of the
PREBEAMST data, together with any diagnostic messages that may be produced.

The output data file containing the generated BEAMST data will be given the name of a four character file name
appended with the characters PB. Hence, for a 4-character file name PRKZ, the resulting data file will be named
PRKZPB.
