摘　　要：温度作用对大跨度空间结构影响显著,常为其控制因素。天津滨海文化中心图书馆为超大跨连体结构,主体为框架-支撑结构。采用MIDAS/Gen有限元软件对该大跨连体结构进行温度响应分析,包括结构应力分析、结构变形分析、支座反力分析以及楼板应力分析等,并且由温度单独作用递进至温度参与荷载组合进行整体结构分析。分析结果表明:温度对该大跨连体结构各项指标影响较大,在结构设计时需要考虑温度作用,在施工中需采取相应的措施对温度效应予以控制。The effect of temperature has significant influence on large-span spatial structure,which is one of the control factors. The library in Tianjin Binhai Culture Center is a large-span connective structure with frame-support system. The finite element software of MIDAS/Gen was used to analyse the temperature effect on the large-span connective structure,including the stress analysis of the structure,the deformation analysis of the structure,the counteracting force analysis and the floor stress analysis. The temperature analysis of the structure was translated from temperature effect only to the one with other effect. The analyzed results showed that temperature effect has significant influence on the large-span connective structure. Temperature effect should be considered when doing the structure design and some corresponding measures should be taken to control the temperature effect during its construction.
