Failure of Pultruded GRP Angle-Leg Junctions in Tension
G Turvey (Lancaster Univ) P Wang (Schlumberger)
Junction tensile strengths and failure modes are reported for two thicknesses of pultruded
GRP angle. The strengths of the thinner angles vary by 30% to 78%, whereas the thicker
ones vary by 3% to 7%. The larger range of strengths is due to inadequate lay-up control in
the thinner junctions. (A1:1)

Design and Fabrication of a GFRP Road Plate
L Antognelli (Magnytude) D Hearn, S Aivazzadeh (LRMA)
A robust lightweight GFRP plate was developed for temporary hole cover during road works.
The sandwich structure, made by vacuum assisted wet layup was validated by FEM analysis
and load testing to rupture before issuing to road works teams. Main objective was man
handling by one or two men thus avoiding mechanised aid. (A1:2)

Non-Linear Properties of Coated Fabrics used in Tensairity Structures
C Galliot, R Luchsinger (EMPA)
The yarn-parallel and shear behaviour of PVC-coated polyester fabric is investigated. From
biaxial tensile test results a simple material model is proposed and included as a Usermat in
Ansys. It is used for the finite element analysis of Tensairity girders. (A1:3)

New Composite Poles for Electrical Lighting, Transport and Distribution
J Nunes (Minho Univ) J Silva (ISEP) J Ferreira (Polight) A Marques (Univ of Porto)
The manufacture, geometrical and mechanical design of new composite poles made from
glass fibre reinforced thermosetting and thermoplastic matrix composites (GRP) were studied
and validated in according to the major national and international standards through
advanced computational methods (FEM) and mechanical tests. (A1:4)

Modeling of Dynamic Properties of the Composite Shell for TV Tower
M Cerny, P Plesinger (Czech Technical Univ)
A dynamic properties of composite shell have been investigated experimentally and
numerically. Eigenvalues have been evaluated by impact testing from output signal in the
mesh of points and their frequency spectrum. The eigenvalues have been further calculated
numerically by QR iteration of the finite element method and compared. (A1:5)

Design Guidance for Bolted Connections in Structures of Pultruded
Shapes: Gaps in Knowledge
T Mottram (Univ of Warwick)
To help engineers and architects use pultruded FRPs in structures there is an undertaking to
prepare an American pre-standard. Design of connections will correspond to those types
used in practice. This paper presents our gaps in knowledge and how they can be addressed
for the design provision to correspond to that for other material standards. (A1:6)

The Pullout Test of a FRP Rebar within a Nanoclay/Concrete Block
W-C Liao, P-H Hung, M-C Lee (Feng Chia Univ)
The FRP (fiber reinforced plastic) rebar with good corrosion resistance and high
stiffness weight ratio is a good alternative of a steel reinforcement for environmental
deterioration prevention. In this study, a filament winding technique is applied to
commercially available FRP rods (with smooth surface) to produce different winding
pitch and lug height.

Strains of Eccentric Compressed RC Columns Strengthened with CFRP
Materials
T Trapko, M Kaminski, M Musial (Wroclaw Univ of Tech)
The subject of conducted experimental studies was analysis of influence of compressive force
eccentricity on strains and effectiveness of strengthening of eccentric compressed reinforced
concrete columns strengthened with CFRP strips and sheets. (A1:8)

Durability of the Composite to Concrete Adhesive Bond under
Accelerated Ageing
K Benzarti, M Quiertant (LCPC) C Aubagnac, S Chataigner (Lab Régional d’Autun)
The durability of concrete beams strengthened by bonded composite materials has been
investigated. Time evolution of the concrete/composite adhesive bond strength was studied
under controlled ageing conditions, by using different mechanical tests. Structural evolutions
of the polymer adhesive during ageing were also studied by DSC analyses. (A1:9)
