摘　　要：通过有限元分析软件ANSYS分析了设置整浇垫块的混合结构房屋承重纵墙的梁端约束力矩,将有限元分析结果与按框架计算而得的梁端弯矩进行了比较,分析表明梁端约束力矩达到了按框架计算的梁端约束力矩的60%左右,并讨论了梁端约束力矩的变化规律。Using finite element analysis soft ware ANSYS to analyse the restriction moment on the beam end of bearing longitudinal walls with casting bearer,the result of finite element analysis is compared with the moment on the beam end calculated with the rigid joint of frame. The analysis suggests that the restriction moment on the beam end equals to about 60% of the moment on the beam end calculated with the rigid joint frame.The restriction moment change rule on the beam end is also discussed.
