地下室温度应力有限元计算与实际应力检测对比分析

Finite element calculation of temperature stress in the basement with the actual stress test analysis

地下室裂缝是当前设计中经常遇到的问题,针对这一问题,本文从理论温度有限元计算入手,再结合现场预埋应力计,进行数据监测分析,从而找到地下室顶板、侧墙在温度作用下的应力分布规律以及混凝土温度变化规律。

Problem is often encountered in the current design of basement crack. For this problem,starting with this article from the theory of finite element calculation of temperature,combined with embedded strain gauges,and monitoring and analysis of data,to find temperature and stress distribution of concrete under the action of temperature variation in the basement roof and wall.
