摘要
利用有限元分析软件,对某大跨度网架起步架递增搬起法的施工过程进行了模拟分析,探讨了三种不同拉索方案结构的内力及变形特征,结果表明,方案一中结构的内力及位移最小,是该大跨度网架结构施工方案的最佳选择。
The paper adopts the finite element analysis software, undertakes the simulation analysis of the construction process of the incrementallaunching method for some large-span space truss, explores the internal force and deformation of the three stretching cable schemes, and indicates the first scheme has the smallest internal force and displacement, which can be regarded as the optimal option for the construction scheme of the large-span space truss structure.
