摘　　要：针对混凝土多孔砖砌体结构墙体温度裂缝问题进行了有限元模型模拟分析,提出了通过ANSYS软件模拟出设置不同间距控制缝模型的温度应力的方法,进行了不同间距控制缝设置对结构温度应力影响的研究,给出了控制及预防砌体结构墙体温度裂缝产生的若干措施,解决了混凝土多孔砖砌体结构设计以及施工的问题。This paper made finite element modeling analysis on wall temperature crack problems maiuly according to perforated concrete brick masonry structure. Proposed temperature stress methods by ANSYS software simulation of different spacing control joint models, researched the influence of structure temperature stress to different spacing control joints, put forward several measures control and prevention of temperature cracks in masonry structure wall, solved the problems of concrete perforated brick masonry structure design and construction.
