[提要]  利用彈性力學(xué)理論，在不作平截面假定的情況下，從理論上推導(dǎo)出無翼緣墻體和帶翼緣墻體的應(yīng)力分布函數(shù)，初步探討了砌體結(jié)構(gòu)墻體抗側(cè)承載時(shí)的剪切滯后問題，進(jìn)一步分析了翼緣、樓板的影響，并與采用平截面假定時(shí)的常規(guī)情形作比較，得出了一些較有意義的結(jié)論。

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
