摘要
温度效应是超长混凝土结构设计时需要考虑的主要问题,本文介绍了温度效应的特点、取值及常用的设计方法,并以佛山市某展览馆为例,分析了超长地下室顶板的温度应力分布特点,考虑温度荷载前后的梁、柱内力变化,以及根据温度效应分析结果所采取的设计措施。
The tempeture effect is one of the main factors that should be considered when designing the over-length concrete structure. In this paper,the fectures,value-taken,and commonly used design method of tempeture effect are introduced. Taking a exhibition hall in Foshan for example,the distribution features of stress on top-roof and the changes in inner-force of beams and columns that considering the tempeture effect are also been described. In the end,the design measuers based on the tempeture effect analysition are provided.
