［摘要］随着功能的需要，挑梁的悬挑长度和上部荷载都有着不同程度的增大。为了防止与挑梁下界面接触的砌体局部受压承载力不足，在挑梁下加设刚性垫块是工程措施之一。利用ANSYS软件对砌体结构挑梁下有、无刚性垫块两种情况进行了有限元分析，根据数值分析结果，对挑梁下加设刚性垫块的砌体局部受压计算提出了建议。

Abstract:With the growing need for new application, the length of cantilever beam and the upper load have been increased to varying degrees. In order to prevent the masonry under the cantilever beam from being inadequate of local compressive bearing capacity, setting a rigid cushion block under the cantilever beam is one of the engineering measures. Finite element method was used to analyze the differences between the masonry structure with and without the rigid cushion block under the cantilever beam. According to the results of numerical analysis, recommendations were given for the calculation of the local compressive bearing capacity of masonry structure with the rigid cushion block under the cantilever beam.

Keywords:cantilever beam; local compression; rigid cushion block; finite element analysis
