| 摘 要： | 索结构在实际的工作时表现出极强的几何非线性,尤其是面内应力和面外刚度的相互耦合作用,即应力刚化.本文将应力刚化的影响计入到空间杂交索结构构件的几何非线性分析中.分析结果表明,考虑应力刚化的索结构更加符合实际的受力状态.

| Abstract: | There are geometrical nonlinearities of cable structures in actual work.At the same time,stiffness outside surface and that in surface are coupled.In this paper,effect of stress stiffening are considered in the geometrical nonlinear analysis of cable structures.Numerical results show the capability of cable structures accords with the actual structures by considering the stress stiffening of cable elements. |

| Keywords: | geometrical nonlinearity stress stiffening cable structure |
