超长混凝土结构温度应力影响分析

Analysis on Influence of Temperature Stress of Ultra-Long Concrete Structures

温度应力是超长结构设计中重点探讨的问题之一。本文介绍了某体育馆超长框架结构温度应力分析及设计,探讨了温度荷载的确定,并通过YJK建模计算,分析了温度应力下结构变形及楼板应力分布,根据分析结果提出来相关控制温度应力的措施,为今后类似工程设计提供一定的借鉴作用。

Temperature stress is one of the key problems in the design of ultra-long structures.In this paper,the analysis and design of temperature stress of ultra-long frame structure of a gymnasium are introduced,the determination of temperature load is discussed,and the structural deformation and floor stress distribution under temperature stress are analyzed through YJK modeling calculation,and relevant measures to control temperature stress are proposed according to the analysis results,which provides a certain reference for similar engineering design in the future.
