张弦桁架施工阶段平面外稳定性研究

Study on Out-of-plane Stability of Truss String Structure During Construction

通过吊装阶段的动力分析,对张弦桁架结构平面外稳定性进行了研究,分析了张弦桁架动态吊装过程对结构平面外稳定的影响,指出在正常设计条件下,吊装过程中结构的平面外稳定性是较易满足的。

In this article, authors study the out-of-plane stability of truss string structure through dynamic analysis during hoisting construction, and analyze dynamic hoisting course effect on out-of-plane stability of the structure. It is indicated that out-of-plane stability can be meet easily during hoisting construction, if the structure is designed normally.
