（悉地国际设计顾问(深圳)有限公司，上海 200235 ）[摘要] 超长结构未设置伸缩缝或设缝间距超出规定限值时，由于温差及混凝土收缩的作用效应积累，会产生较大的约束应力，此时需分析温差效应对结构水平及竖向构件的影响。利用有限元软件MIDAS BUILDING,研究分析温差效应对具体超长结构的影响，为合理设计提供依据。中图分类号：TU375 文献标识码：A 文章编号：1002-848X(2013)S1-0662-04Influence of temperature difference effect on super long multi-layer structureMiao Liuhua, Guo Rui, Xia Guanghong, Zou Wenbao, Yan Ping(CCDI Group,Shanghai 200235,China)Abstract: Super long structure without expansion joint or joints is higher than the specified limit, due to the temperature difference and shrinkage of concrete accumulation, will have great constraint stress, which need analyzing the effect of temperature difference on horizontal and vertical members of structure. Research and analysis of temperature difference effect on specific super long structure, providing the basis for rational design, with finite element softwareKeywords: super long building, super long structure, influence of temperature difference, temperature stress, finite element
