砌体结构温度场及温度应力分析

Analysis of Temperature Stress of Masonry Structure with FEM

对砌体结构墙体与屋面板的温度场进行了实测分析,得到了砌体结构墙体与屋面板随时间的温度分布,给出了砌体结构建筑温度场的变化规律,在实测温度场的基础上,用有限元法对整体结构进行了温度应力分析,并给出了考虑于缩影响的温度应力计算方法。

Through the analyzing of temperature field of masonry structure's wall and roof,temperature distributing of masonry structure's wall and and roof is acquired,and the changing lawof temperature field is presented.Based on the factual temperature field,temperature stress is analyzed using the finite element method for the experimental building and the calculation method of temperature stress is presented when the effect of material shrinkage is concerned.
