摘　　要：该文对采用钢丝网水泥砂浆加固的损伤剪力墙进行低周往复循环荷载作用下的有限元分析。首先分级加载情况,然后从滞回性能、刚度退化、耗能与延性等方面,综合分析钢丝网水泥砂浆用于加固损伤剪力墙的加固效果。结果表明:采用钢丝网水泥砂浆加固后,损伤剪力墙的承载力提高了17.3%,刚度和延性均有所提高,验证了钢丝网水泥砂浆加固法的可行性。In this paper,the finite element analysis was conducted on damaged shear walls strengthened with steel wire mesh cement mortar under low cyclic loading.First the loading was graded,and then the reinforcement effect of ferro-cement mortar used to strengthen damaged shear walls was comprehensively analyzed from the aspects of hysteretic behavior,stiffiiess degradation,energy consumption and ductility.The results showed that the bearing capacity of the damaged shear wall is increased by 17.3%,and both the stiflhess and ductility are improved,which verifies the feasibility of the steel mesh cement mortar reinforcement method.
