摘　　要：为了研究碳纤维网格在砖墙加固中的作用,设计了4个试件,进行低周往复荷载试验。试验结果表明,碳纤维网格与高延性砂浆结合成形成的复合加固层与砖墙未出现剥离现象,裂缝分布均匀,砖墙与加固层协同受力及变形性能较好,可以显著提高墙体抗裂性能和极限承载力。In order to study the seismic performance of CFRP mesh in brick wall reinforcement,four specimens are designed and tested under low cyclic loading.The test results show that the composite reinforcement layer formed by the combination of carbon fiber mesh and ductile high-strength mortar has no peeling phenomenon with the brick wall,the cracks are evenly distributed,the brick wall and the reinforcement layer have good synergistic stress and deformation performance,which can significantly improve the crack resistance and ultimate bearing capacity of the wall.
