| Abstract: | This paper presents a plate truss model and its calcul ating method of prestressed concrete members under combined bending, shearing and torsion. The calcula ting formulas have been set up and computer programs have been compiled according to the conditions of balance of force, deformation compatibility and stress strain relations. The theory values agree very well to the experimental data. |
