摘　　要：为解决强震后严重受损砌体窗间墙难以快速修复问题,提出一种承压抗剪型金属阻尼器替代墙肢的修复方法。根据窗间墙受损特征,数值建模设计与其受力特性吻合的阻尼器,选取多层砌体墙受损模型分别进行修复前后的拟静力对比试验,分析两模型的破坏特征、滞回特性、刚度退化规律、耗能与变形特征等抗震性能。研究结果表明:承压抗剪型阻尼器替换修复技术可快速改善砌体的抗震性能,增强结构的变形能力,是满足震后受损砌体结构功能迅速恢复的一种简捷修复方法,为消能减震技术在砌体结构中的应用提供借鉴。An alternative repair method in compressive-shear metal damper is introduced to eliminate the technical obstacle of repairing severely damaged masonry piers rapidly after strong earthquake.According to the piers'damage pattern,the mechanical mechanism of dampers is determined by numerical simulation.The quasi-static comparative tests of multi-story masonry models before and after damage are carried out,and the hysteretic behavior,skeleton curve,stiffness degradation,deformation,ductility and energy dissipation of the two walls are comparatively analyzed.The research results indicate that the proposed repair technology can quickly improve the deformation capacity of the masonry.It is a simple method to satisfy the rapid recovery of damaged masonry structure after earthquake,which provides an effective way for the application of energy dissipation technology in the retrofit of damaged masonry structure.
