［摘要］由于建筑造型和功能的限制，济宁创意大厦两个方向均不设置伸缩缝，为双向超长钢筋混凝土结构。采用有限元软件ETABS和MIDAS Building对结构进行整体建模计算及详尽的温差效应分析。介绍了分析中结构综合温差的取法以及温降作用效应的折减方法，并得出了温差效应的分布特点。在分析结果的基础上，对本工程采取了相应的措施来解决温差效应带来的不利影响，以满足规范要求。介绍的温差效应分析方法概念明确、设计方便，可供类似工程参考。

Abstract: Due to architectural facade and functional restrictions, there are no expansion joints in two directions of Jining Chuangyi Building, which is a bilateral overlong reinforced concrete structure. The finite element software ETABS and MIDAS Building were used in integral modeling and calculations, and temperature variation effect was analyzed in detail. The general temperature variation selection method and reduction method of structural temperature drop effect were introduced. The distribution features of structural temperature variation effect were obtained. Based on the analysis results, corresponding measures were taken to solve the adverse effects of temperature variation effect in this project in order to meet the requirements of the code. The method in analysis of temperature variation effect is clear in concept and convenient in design, providing reference for similar engineering practice.

Keywords: overlong reinforced concrete structure; temperature variation effect; general temperature variation; expansion joint
