摘要
本文介绍了考虑索单元松弛跟踪的空间索桁结构非线性有限元全过程分析方法。并以典型的鱼腹形索桁结构为例,探讨了空间索桁结构的力学性能,以及在荷载作用下结构几何体系演变的特征。本文对新型空间索桁结构的研究和工程应用具有指导意义。
A nonlinear finite element method considering the slack of cable elements is proposed in this paper for analysis of spatial cable truss structures. Taking a cable truss structure with a shape of fish abdomen as an example, the mechanical behavior of the structure is discussed in detail, as well as characteristics of geometrical system changing under external load. Some conclusions are drawn from this paper which will guide the further research and application of new spatial cable truss structures.
