［摘要］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。［关键词］稳定分析; 弯扭构件; 配重; 钢屋盖中图分类号：TU393.3 文献标识码：A 文章编号：1002-848X(2015)14-0040-06
Structural design of main preface hall of Tien Lake International Conference Exhibition Center in KunmingZhu Qinghua（China Majesty Structure Design Office Co., Ltd., Shanghai 200135, China）Abstract: The steel roof of the main preface hall of Tien Lake International Conference Exhibition Center in Kunming has a complex space form which consists of multiple geometric shapes. The structural system of the steel roof for main preface hall was introduced, and structural layout schemes for the steel roof structure and its vertical bearing system were provided. The main calculation results were presented by analyses of various finite element programs, including dynamic characteristics of the whole structure, regularity of the structural plan and stability analyses of the atrium columns. Additional analyses of key regions of the atrium columns were provided and better design ideas were given to improve the mechanical performance which used methods of counterweight and increasing steel strength locally.Keywords: stability analysis; bending-torsion component; counterweight; steel roof
