Paper Title:
Calculation for Torsion Strength of Prestressed Concrete Beams Based on Fixed-Angle Softened Truss Model
  Abstract

The calculation model for torsion strength of prestressed concrete beams (PCs) under pure torsion is deduced theoretically based on Fixed-Angle Softened Truss Model (FA-STM) and an efficient algorithm for the model is proposed. The calculated values of torsion strength and the Torque-twist curves predicted by the proposed method agree well with these obtained from tests for the two specimens available in literature. These indicate that the proposed method can not only calculate the torsion strength efficiently but can also predict the load—deformation curve of the PCs.
