昆明滇池国际会展中心展馆主序厅钢屋盖曲面由多种几何形状组成,空间造型复杂。介绍了主序厅钢屋盖的结构体系,给出了钢屋盖结构及其竖向承重结构的布置方案;通过多种有限元软件对主序厅进行计算分析,给出了整体结构的动力特性、结构平面规则性及中庭柱的稳定分析等主要计算结果;对树形柱的关键部位进行了补充分析,给出了通过配重及局部提高钢材强度的方法来改善树形柱受力性能的设计思路。
Main Hall of Kunming Dianchi International Convention and Exhibition Center Hall The steel roof surface consists of a variety of geometric shapes, spatial modeling complex. The structure system of the steel roof in the main hall is introduced, and the layout of the steel roof structure and its vertical bearing structure is given. The calculation and analysis of the main hall is carried out by a variety of finite element software, and the power of the whole structure is given The main calculation results of the stability analysis of the atrium column and the plane regularity of the structure and the stability of the atrium column are analyzed. The key parts of the tree column are supplemented and analyzed, and the force performance of the tree column is improved by the method of counterweight and local increase of the steel strength Design ideas.
