电缆桥架结构的稳定性分析

The Analysis of Stability of Cable Frame Structure

电缆桥架广泛采用薄壁结构,其失效涉及到强度、刚度和稳定性等问题,而且薄壁件又有非线性问题,故桥架生产厂家难以考虑这些因素。笔者从理论上对电缆桥架的强度、刚度和稳定性进行讨论,并通过试验验证得到的结论可供桥架设计者参考。

Thin-wall construction is widely used in cable frame,its failure mode refers to strength,rigidity and stability. And it has nonlinear problem.But it is difficult for manufacturer to think about those problems.This paper discusses those points and draws some conclusions on the theoretical principle,and proves those conclusions from the test.Those conclusions can serve as a reference in the design of cable frame.
