[摘要] 对株洲体育中心工程大跨度、形状复杂的雨篷结构的风洞试验结果与荷载规范取值进行了经济合理性和安全性分析。通过方案比较和分析，对雨篷主体结构选择较经济、易施工的焊接球空间网架形式，并对复杂结构的支座节点和支撑柱进行合理的布置和设计，如采用支座群嵌固解决很不规则网架结构的倾覆力和扭曲力问题，采用钢管混凝土叠合斜柱、钢管混凝土长柱以解决奇形柱的受力和变形问题。经过建成后一段时期的正常使用过程，工程的雨篷网架及下部承力结构不仅满足设计规范要求，还具有较好的设计合理性和经济效果。

Abstract: It makes an analysis of economic reasonability and safety of results of wind tunnel experiment and the load value of canopy structure with super-span and complex shape of Zhuzhou Sports Center project. Through comparing and analyzing the schemes, choose a more economical and easy construction of the welding ball stereoscopic latticed framed form for the main structure of canopy structure, and for the complexity of the bearing structure ofjoints and support column well-justified layout and design, such as the use of support group fix solve the irregular of latticed framed structure and the overturning force and the distorted force problem, the use of inclined composite concrete-filled steel tube columns, composite concrete-filled steel tube long columns to resolve the irregular shape columns of the problem of force and deformation. After the normal service period, it shows. that the latticed framed structure for canopy and the supporting structure below of this project not only meet the requirements of design rules, but also has better design reasonability and economiceffect.
