［摘要］隨著功能的需要，挑梁的懸挑長度和上部荷載都有著不同程度的增大。為了防止與挑梁下界面接觸的砌體局部受壓承載力不足，在挑梁下加設剛性墊塊是工程措施之一。利用ANSYS軟件對砌體結(jié)構(gòu)挑梁下有、無剛性墊塊兩種情況進行了有限元分析，根據(jù)數(shù)值分析結(jié)果，對挑梁下加設剛性墊塊的砌體局部受壓計算提出了建議。

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.
