摘　　要：利用匀质化方法,得到一个三层砌体结构等效体积单元的各力学参数,再运用ANSYS软件对该砌体结构进行了地震反应模拟。最后把计算结果与试验结果进行了对比,二者基本吻合,说明采用砌体匀质化方法进行非线性分析是合理可行的。Masonry is not a homogeneous material. It is difficult to simulate the performance of this material. All parameters of representative volume element of a three-story masonry structure by homogenization method are got, then earthquake is simulated on this masonry structure via ANSYS. Finally, results of experiment with results of simulation are compared, and the two results are indentical. It is proved that the homogenization method is reasonable to analyze masonry.
