摘　　要：采用预制钢筋混凝土墙板加固砌体可以有效提高砌体结构抗震性能。采用传统现浇钢筋混凝土面层和预制钢筋混凝土墙板构件对1∶2全缩尺素砌体墙进行单面加固试验。文中主要通过Midas FEA非线性有限元软件对素砌体墙、现浇面层加固砌体、预制构件加固砌体进行数值模拟分析,结果表明:两种加固方式加固效果相当;采用预制混凝土构件加固砌体,可以有效提高砌体抗震性能,极限承载力提高6.25倍,最大位移降低约10倍。Strengthening masonry with prefabricated reinforced concrete wall panels can effectively improve the seismic performance of masonry structures.A single side reinforcement test was conducted on a 1∶2 full scale plain masonry wall using traditional cast-in-place reinforced concrete surface layer and prefabricated reinforced concrete wall panel components.The article mainly uses Midas FEA nonlinear finite element software to conduct numerical simulation analysis on plain masonry walls,reinforced masonry with cast-in-place surface layers,and reinforced masonry with prefabricated components.The research results show that the reinforcement effects of the two reinforcement methods are equivalent.Strengthening masonry with prefabricated concrete components can effectively improve its seismic performance,increase its ultimate bearing capacity by 6.25 times,and reduce its maximum displacement by about 10 times.
