摘　　要：内外温差是砌体结构产生裂缝的主要原因之一,然而对不同墙体间距下砌体结构在温度荷载下的应力进行的分析很少,本文通过ANSYS分析软件进行15种情况下的特定分析,然后对数据进行整理分析,同时与圈梁构造柱的作用加以比较,能更清楚的了解不同墙体间距对房屋抗温度应力所起的作用,为砌体结构的设计及检测鉴定提供理论上的依据。Temperature difference between interior and exterior account for the major cause of the wall cracking,whereas there is less work done in analysis of tmeperature stress in masonry structure with different interval space between Wwlls.In cooperate with ANSYS,a populr finite element analysis tool,15special cases are studied in this paper.By comparing with ring beam and constructional column,it made clear the effect of the wall arrangement,Conclusions are＇reached with the discussion of the results,and provide a theoratical principle for the design and inspection and rehabilitation.
