摘　　要：为研究加固后砌体结构的抗震性能,本文对全缩尺模型下的预制混凝土墙板加固法与现浇面层加固法的加固效果进行对比分析,并对局部后浇带措施替代传统后浇带连接法的可行性进行研究。结果表明:1)合理配筋设计的局部后浇带可以替代现场通长后浇带的连接措施;2)缩尺模型下的预制混凝土构件加固砌体可有效提高砌体抗震性能。本文研究成果可为类似砌体结构加固方法的设计与研究提供一定的借鉴与参考。In order to study the seismic performance of reinforced masonry structures,the reinforcement effects of the precast concrete wall panel reinforcement method and the cast-in-place surfacing layer reinforcement method is compared and analyzed under the full-scale model,and the feasibility of replacing the traditional back strip belt connection method with local back strip measures is studied.The results show that:1)The local back belt with reasonable reinforcement design can replace the connection measures of the on-site through-length back belt;2)The reinforcement of masonry of precast concrete units under the scaled model can effectively improve the seismic performance of masonry.The results can provide a certain reference for the design and research of similar masonry structure reinforcement methods.
