摘　　要：砌体结构是山西省变电站工程中常见的结构类型。对其进行抗震性能研究通常采用效率低、成本高的结构试验。利用有限元方法对砌体结构抗震性能进行数值模拟研究,结果表明,ANSYS有限元软件可以较为准确地计算地震作用下墙体的开裂荷载、开裂位移,并且可以模拟墙体在地震作用下的应力分布和裂缝开展。此方法可以应用于砌体结构的抗震性能研究,作为结构试验的辅助手段验证对比试验数据的合理性。Masonry structure is a common type of structure in our province substation engineering. The seismic behavior of the masonry structures is usually researched by structure test with low efficiency and high cost. By means of the finite ele- ment method, numerical simulation of masonry structures seis- mic behavior is studied. The results indicate that the ANSYS fi- nite element sottware can calculate cracking load and displace- ment of masonry walls more accurately, and it can be used to simulate the stress distribution and crack propagation of the wall under the seismic action. This method can be applied to research the seismic behavior of masonry structures, and is used to verify the rationality of the experiment data as an auxiliary means of structure test.
