摘　　要：位于框架梁上和由纵向梁承托的横向组合墙体，由于梁的变形而使墙体的抗侧承载力及刚度均有不同程度的降低，这对底层框剪和底层大开间上部小开间组合墙体房屋的抗震性能将带来影响。本文研究了这些二、三层横向组合墙体的强度和刚度变化情况，并分析了其中的主要影响因素。The lateral loading capacity and lateral stiffness of composite masonry wall supported on R/C frame beam or longitudinal wall beam would be decreased due to the deformation of the beams.This phenomenon is important for the masonry building supported by lower R/C frames when the lateral stiffness ratio would be effected the seismic performance of this type of buildings.In this paper,the lateral loading capacity and stiffness of second storey and third storey composite masonry wall are studied and some commentaries are given.
