摘  要：
运用SOLID65单元分别模拟砖砌块和砂浆,运用Contact174和Targe169接触对单元模拟这两种材料间在不同剪压受力状态下的非线性接触特性,得出了与试验结果基本一致的剪压破坏形态和相关曲线.同时,程序计算也验证了普通砖砌体结构在压应力不断增大的条件下,其剪压复合破坏形态依次为:滑移破坏、剪压破坏、斜压破坏.

摘  要：
By using SOLID65 element to simulate brick and mortar and using contact pair of Contact174 and Targe169 elements to simulate nonlinear contact performance under shear-compression loading,the paper obtains a calculating curve and failure criteria for masonry structure accorded with tests.Results of analysis are testified that along with increasing compressive stresses,the failure criteria of masonry structure under combined shear and compression are as follows:(a) failure of the bend joints by friction;(b) failure of masonry as a result of exceeding the tensile strength of masonry unit;and(c) failure of masonry as a result of exceeding the compressive strength of masonry unit.
