Abstract Based on equilibrium and compatibility, a general analysis procedure is developed
for cracked prestressed and partially prestressed concrete composite sections in the
elastic range of behavior. Direct equations are derived for the strains and stresses in
the constituent materials taking into account the change in prestressing force due to
the application of loads. Solutions for the special cases of uncracked composite
sections, cracked and uncracked noncomposite sections as well as expressions for
the cracking and decompression moments are also presented. A parametric
analysis is conducted to study the effects of various parameters on the stresses and
stress ranges in the constituent materials. An example is developed to illustrate the
application of the method.
