Torsional Analysis for Prestressed Concrete Multiple Cell Box

The softened truss model theory applied to a prestressed concrete multiple cell box is developed in this study. In this theory, the concrete torsional problem is solved by combining equilibrium and compatibility conditions and constitutive laws of materials. Until now the theory has been applied only to the case of pure torsion with a single cell section. An algorithm is presented to
