EXPERIMENTAL RESEARCH ON SEISMIC BEHAVIOR OF PREFABRICATED SHEAR WALL WITH ENERGY DISSIPATION BY VERTICAL JOINTS

摘要: 基于装配式剪力墙结构“强水平缝弱竖缝”的设计理念,设计了一字形及T形装配式剪力墙试件,对其进行低周反复荷载试验,并与现浇剪力墙试件的抗震性能进行对比。结果表明:竖缝采用阻尼器连接的装配式剪力墙整体工作性能良好,其承载力与现浇剪力墙试件相差不大,但其延性系数好于现浇试件。阻尼器在受力过程中耗能,对墙体起到了一定的保护作用,满足强水平缝弱竖缝的设计要求。Abstract: Based on the concept of "strong horizontal seam and weak vertical seam" of prefabricated shear wall structure, the specimens of the prefabricated shear wall and the cast-in-place shear wall were designed.Based on the results of quasi-static loading test,the results showed that the overall working performance of the shear wall connected by damper was good, the bearing capacity was not very different from that of the cast-in-place shear wall specimen, but the ductility coefficient was obviously better than that of the cast-in-place shear wall specimen.The damper dissipated energy in the process of force, and played a certain protective role on the wall. In the process of force, the wall could meet the design requirements.
