从某体育馆工程谈空间网格结构内力分析

复杂空间网格结构设计不仅要考虑到结构边界合理的模拟,同时应特别注意在施工过程中由于支座侧向变形及施工工序引起的安装误差,造成的次应力二次分配问题。本文通过某一具体工程空间网格设计,分析了从方案到施工中的空间网格结构中构件的内力变化,提出了此类结构设计与施工中应特别注意的问题,为工程实践提出有益的参考。

Analyse on Project of Spatial Grid Structure

For the design work of complicated spatial truss, it should be considered that not only proper boundary conditions,but also the stress redistribution caused by the transverse displacements of the bearings during the construction, and the error of the installation. in this thesis, a serial problem is analyzed through design of a space gird structure from plan to struction.
