［摘要］大连市体育中心体育场罩棚结构采用骨架支承式ETFE气枕膜结构，气枕覆盖面积超过德国安联球场，是目前国内规模仅次于“水立方”的ETFE气枕膜建筑，对其骨架支承结构和气枕结构的设计与分析进行了详细的介绍。首先根据各荷载工况对钢桁架结构的静力性能和动力特性进行了详细分析，在此基础上采用反应谱法和时程分析法对钢桁架结构分别进行了多遇地震和设防烈度地震作用下的结构响应分析，并进行了罕遇地震作用下的动力弹塑性时程分析，指出结构具有足够的强度和刚度储备；然后对该钢桁架结构进行了考虑几何非线性和材料非线性的稳定性分析，结果表明结构稳定性能良好，满足规范要求；最后对气枕结构基本参数的确定、计算与分析以及节点构造做了详细介绍。

Abstract: Skeleton-supporting ETFE cushion membrane structure is used in Dalian Sports Center Stadium’s canopy shell. Cushion structure covers more area than Germany Allianz Arena and it is currently the second largest cushion structure after the ‘Water Cube’ in Beijing. Design and analysis of skeleton-supporting structure and cushion structure were introduced in detail. First, static and dynamic characteristics of the steel truss were analyzed in detail based on different load conditions. Based on this, response analysis of the steel truss under frequent and intermediate earthquakes was conducted using response spectrum method and time-history analysis method respectively. Dynamic elastic-plastic time-history analysis under rare earthquake was carried out as well. Conclusion is drawn that the steel truss has enough strength and stiffness reserve. Moreover, the stability analysis of the structure was conducted with the consideration of geometrical and material nonlinearity. The results show that the stability of the structure can meet the demands of code. Finally, the basic parameter determination, the design and the joint construction of the cushion structure were illustrated specifically.

Keywords: Dalian Sports Center; canopy shell; steel truss structure; cushion structure
