[提要]  利用解析方法和试验模态分析方法研究了高层砖砌体房屋在地震力作用下的破坏机制，指出其破坏机制为弯曲型破坏，这一点与普通砖砌体结构的剪切型破坏机制是不同的。提出的高层砖砌体结构地震破坏机制，可供该类结构的抗震设计参考。还分析了具有构造措施的砌体结构的抗震特性。

By using analytic method and mode test method, the failure mechanism of high-rise masonry structure under earthquake has been studied. It is pointed out that the failure mechanism of a high-rise masonry structure is bending deformation failure which is different from the shearing one of an ordinary masonry structure. A precious information for the eaIthquake-resistant design of high-rise masonry structure has been put forward. The earthquake-resistant character of high-rise masonry structure with constructing measure has also been analyzed.
