（中国航空工业规划设计研究院，北京 100120）[摘要] 国内对于超长结构的温度应力已做了很多研究，但对于超长开口环形平面结构确很少有实例参考。本文则以实际工程为例，分析开口环形超长结构的温度效应，从变形规律、内力、徐变、温度缝设置等多个角度进行阐述，并找出规律。同时对不同结构进行经济性比较，得出相应结论。对类似工程有较高的参考价值。[关键词] 开口环形结构;楼板温度变形;温度应力;经济性中图分类号：TU119.22 文献标识码：A 文章编号：1002-848X(2013)S1-0672-05The analysis of temperature effect of opening annular plane structureJin Laijian, Jing Hui, Xie Jun, Wang Degang(Abstract: A lot of research about the temperature effect of long structure have been done up to now. However, the researches about extra-long opening annular structure are not enough. Thus, the temperature effect of the opening-annular-long structure was analyzed in this article, and corresponding conclusions were drawn. At the same time, an economical comparison of different structures based on temperature effect was also explained and analyzed. The conclusion we got have a high reference value for similar projects.Keywords: Opening annular structure; Temperature deformation of slab; Temperature stress; Economical efficiency作者简介：景辉，硕士，一级注册结构工程师，Email: lojhve@126.com。
