[摘要]介绍了新疆喀什体育场罩棚的钢结构设计，分析了钢结构设计中温度作用对结构的影响，并对钢结构罩棚及支撑钢结构屋面的混凝土柱在大震作用下的地震响应进行论述。在罕遇地震作用下，上部钢结构仅在悬挑端部局部出现构件截面部分屈服。对于支撑钢屋盖混凝土柱大量出现My和Mz铰，局部破坏程度达到构件明显破坏。大震作用下，支撑钢屋盖的混凝土柱纵向配筋率需要加强以提高抗弯能力。

Abstract: The design of steel structure of Xinjiang Kashi Stadium Canopy was introduced, the temperature effect of steel structure design of structure was analyzed, and the seismic response of reinforced concrete column steel roof and supporting steel roof under major earthquake was discussed. Under the action of rare earthquake, the steel structure of the upper part of the steel structure is only partially in the section of the cross section of the suspension. For the support of the steel roof concrete columns, a large number of My and Mz joints, the degree of local failure to achieve significant damage. Under the action of earthquake, the longitudinal reinforcement ratio of concrete columns supporting the steel roof should be strengthened to improve the bending resistance.

Keywords: Kashi Sport Stadium； radial cantilever truss; super length structure; temperature stress
