摘　　要：高强钢绞线网-聚合砂浆复合面层加固法是一种新型加固工艺,具有耐火、耐腐蚀、耐老化的优点。通过2个采用钢绞线网-聚合物砂浆加固的钢筋混凝土框架节点(其中1个节点震损后再加固)和1个对比节点的低周反复荷载试验,比较了不同加固方式的加固效果,分析了相应的加固机理。研究结果表明,采用该技术加固节点能有效提高节点的抗剪承载力和耗能能力。Rehabilitation of members by composite cover of wire mesh and polymer mortar is a new method of structural strengthening with the advantages of resistance to fire, corrosion and ageing. Two beam-column joints strengthened by composite cover of high strength wire cable mesh and polymer mortar, and one un-strengthened joint are tested under lowcycle reversed load. The effect of different rehabilitation schemes on the shear-resistance capacity of the joint and the strengthening mechanism are analyzed. The results show that the beam-column joints strengthened with wire cable mesh and polymer mortar are beneficial to the shear capacity and seismic behavior of the joints.
