The application of membrane-element theory in the calculation for compound torsion members

以软化空间桁架模型为基础,应用薄膜元理论对复合受扭构件进行了全过程分析,对构件的破坏荷载和变形进行了计算,其结果与试验结果相比较,符合较好。

Membrane-element theory is applied in the calculation for torsion members ,which is based on variable-angle space truss model. With this method, the whole-process analyses of compound torsion members are done, and the capacity and deformation are calculated ,which are compared with experimental results and shown to be in good agreement.
