摘　　要：我国现行砌体结构设计规范所规定的最大伸缩缝间距仅仅针对一字型房屋。该文利用ANSYS软件对比分析了“一字型”和“L型”二种不同平面砌体结构在温度荷载作用下墙体变形、应力及其分布规律,得到了窗间墙的轴力、剪力与房屋长度的关系式,依此分析了“一字型”和“L型”结构墙体最大伸缩缝间距,并根据墙体变形分布规律得出了伸缩缝设置的部位。The maximum expansion joint spacing stipulated in the current design code of masonry structures in China is only for"transverse line-shaped"houses.This paper uses ANSYS software to compare and analyze the wall deformation,stress and distribution law of two different plane masonry structures,"transverse line-shaped"and"L-shaped"under temperature loads.The relationship between the axial force and shear force of the wall between the windows and the length of the house is obtained.Based on this analysis,the maximum expansion joint spacing of the"transverse line-shaped"and"L-shaped"structural walls is analyzed,and the location of the expansion joints is obtained according to the wall deformation distribution law.
