| 摘 要： | 撑杆是张弦桁架中不可缺少的组成部分,在整体结构刚度形成中起着非常重要的作用,撑杆的失稳将导致结构整体刚度急剧降低及拉索松弛.在张弦桁架形态优化设计基础上,详细分析了撑杆数目变化对张弦桁架形态结果的影响,作为张弦桁架形态优化设计的一部分,提出了几种布置撑杆的方法,并建立了相应计算模型进行分析;同时对撑杆与结构的稳定性进行了研究,结果可为张弦桁架设计时提供参考.

| Abstract: | Struts can't be omitted in truss string.It is very importnt in forming stiffness of the structures.Loss of stability of a strut will introduce great decrease of the stiffness and loss of the string.On the basis of shape-state analysis of optimization design of truss string structure,the effect of the number of strut is studied in detail,and some methods of strut design and corresponding model are presented in this paper.At the same time,the stability of strut and structure are studied.This provides reference for the design of truss string structure. |
