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 a significant impact on the long-span spatial structure, which is often the controlling factor. Tianjin Binhai Cultural Center Library is a large span of the Siamese structure, the main frame - the support structure. The temperature response analysis of the long-span Siamese structure is carried out by MIDAS / Gen finite element software, including structural stress analysis, structural deformation analysis, bearing reaction force analysis and floor stress analysis, etc., Combination of the overall structure analysis. The analysis results show that the temperature has a great influence on the indexes of the long-span continuous structure, and the temperature needs to be considered in the structural design. Corresponding measures should be taken to control the temperature effect in the construction.
