摘　　要：高强钢绞线网-聚合物砂浆加固技术(SMPM)是一种先进的新型加固技术。本文利用通用有限元软件ANSYS对该加固技术加固RC梁进行了数值模拟分析,包括对抗弯及抗剪加固梁的挠度、应变、应力等的分析,并与相关试验结果进行比较,发现分析结果与试验结果吻合较好,为该加固方法提供了有效的理论依据。Rehabilitation of reinforced concrete members with high-strength steel wire mesh and polymer mortar（SMPM） is an advanced means of retrofitting. In this paper, numerical analyses of flexural and shear behaviors of the strengthened RC beams were conducted through the ANSYS finite element program. The mid-span deflection, stain and stress of the beams were analyzed. And the results agree well with the experimental ones, which provides an efficient theoretical analysis to the experimental investigation and application of SMPM.
