摘　　要：本文以某体育会展中心为例,介绍大型空间结构屋盖管桁架钢结构设计的关键技术,包括钢结构整体计算、结构稳定性计算(包括线性屈曲分析和非线性屈曲分析)、弹性时程分析、铰接支座的受力分析和铸钢空心球节点承载力验算的计算分析结果。由于上部钢结构和下部混凝土结构材料特性的差异,对上部钢结构和下部混凝土整体模型进行了分析计算。Take the sport and exhibition center as an example, to introduce the key technology in designing the roof of large space steel tube truss, include the steel structure integer calculation, the stability analysis （include linear buckling analysis and nonlinear buckling analysis）, elastic time-history analysis, hinged support force analysis and cast-steel hollow sphere joint bearing capacity were analyzed deeply, because of the difference between upper steel structure and concrete strueture below, analysis of the whole model was carried out. The method mentioned in this paper may be referred for correlative engineering.
