摘　　要： 以村镇砌体结构房屋中砂浆强度偏低的砖墙为研究对象,提出了一种全新的抗震加固方法:角钢和打包带加固法,并通过低周往复荷载试验,对加固后墙体和原墙在水平力作用下的承载力和变形性能进行了对比分析和研究,从墙体的破坏形态、承载力、变形、滞回特性和耗能性能等多方面进行了抗震性能分析。结果表明,采用本文提出的加固方法可明显提高墙体的抗震性能,尤其是墙体的延性由于打包带的约束作用得到大幅提高。本文的加固方法施工简单、经济高效,有利于在广大农村地区推广应用。 In this paper,the brick walls of low intensity are studied in masonry structures of rural villages,and a new kind of reinforced method is presented：reinforcing walls with steel angles and packing belts.The bearing capacity and deformation properties under lower cycle reversal load are studied by experimental research and analysis.The result about seismic performance is generalized including the failure pattern,bearing capability,deformation,hysteretic curves and energy dissipation,and so on.The result shows that by this kind of reinforced method the seismic performance of the walls is greatly increased,especially the ductility is clearly improved because of the constraint action of packing belts.Based on economics and easily handling,this method is fit for being extended in rural areas.
