| Abstract: | In this paper,the application of membrane-element theory in the calculation for torsion members is studied,which is based on variable-angle space truss theory,taking care of concrete's softening and tension stiffening.The whole-process of loaded member is simulated with iterative numerical analysis method,and the capacity and deformation are calculated,which are compared with experimental results and shown to be in good agreement. |

| Keywords: | membrane-element theory softening tension stiffening nonlinear analysis |
