摘　　要：对混凝土砌块砌体进行了数值模拟,对于影响模拟结果准确性的一些因素包括剪力传递系数的取值、打开关闭压碎、迭代算法进行探讨.应用ANSYS有限元分析软件模拟足尺混凝土砌块墙在水平和竖向荷载共同作用下的受力性能,结果表明足尺墙体的抗剪强度低于砌体抗剪强度指标.得出的结论可供砌体结构设计和研究参考.Concrete block masonry wall was simulated in numerical method. Some factors affecting the accuracy of simulation results were discussed. These factors include the values of shear transfer coeffi- cient, open or closed crushing option and iterative algorithm. Concrete block wall with full size of width under horizontal and vertical loading was simulated with finite element analysis software ANSYS, and the result showed that the full size wall shear strength was lower than masonry. The conclusions can provide references for masonry structure design and research reference.
