DESIGN OF PRESTRESSED CONCRETE BEAMS SUBJECTED TO TORSION

A procedure for designing prestressed concrete beams subjected to torsion, bending and shear is proposed. This procedure uses the current ACI recommendations for reinforced concrete as a basis. The results of tests on four beams that were designed using the proposed method show that the method is satisfactorily conservative and correctly predicts the type of failure. The results of these four tests were also compared to the results predicted by the truss theory and it was found that the truss theory is more conservative and does not adequately predict a compression failure. Finally, the experimental strengths of 379 prestressed beams reported in the literature are compared with the ultimate strengths predicted by the proposed design procedure. The design method was found to be conservative, particularly for I-sections and T-sections. /Author/
