[提要]  利用弹性力学理论，在不作平截面假定的情况下，从理论上推导出无翼缘墙体和带翼缘墙体的应力分布函数，初步探讨了砌体结构墙体抗侧承载时的剪切滞后问题，进一步分析了翼缘、楼板的影响，并与采用平截面假定时的常规情形作比较，得出了一些较有意义的结论。

The shear-lethargy of masonry wall under lateral loading is discussed. Based on the theory of elastic mechanics without the hypothesis of plane section, the function of the distribution of the stress in the masonry wall with wing wall or without wing wall is put forward. Analyzing the affection of wing wall and slab furtherly, significant conclusion is obtained by contrasting with the general results by the hypothesis of plane section.
Keywords: lateral loading; stress distribution; shear-lethargy
