In the present study a nonlinear finite element analysis is carried out on twenty prestressed concrete cantilever beams having different lengths vary from 1.0m to 3.0m with 0.5m increments and subjected to a concentrated torque at the free end using ANSYS V10 finite element package. This study emphasizes on the effect of beam length to depth ratio on the strength, behavior of prestressed concrete beams and effectiveness of prestressing strands in the pre and post cracking stages of loading. This work is part of a PhD research program at the University of Mosul to investigate the non-linear three dimensional behavior of prestressed concrete beams under pure torsion.
