Precast buildings have attarcted worldwide attention because of their significant role in the realization of sustainable urbanization. In this study, a precast buckling-restrained composite shear wall (PBRSW) system is developed, which is assemblied by multiple composite shear wall modules on site. The PBRSW system with three assembly arrangements of the composite shear wall modules, vertical, horizontal and cross arrangements, are designed and explored comparatively to mitigate buckling phenomena and obtain beneficial mechanical behaviours with experiment and simulation methods. To bring insight the seismic performance of the developed system, traditional buckling-restrained shear wall (BRSW) system and steel plate shear wall (SPSW) system are further investigated. The results show that the PBRSW system achieves plumper hysteresis behaviors, higher force-bearing and energy-dissipation capacities, and better ductility performance than that of the other two systems. Buckling phenomena of the PBRSW system are restrined effectively, and its maximum out-of-plane displacement is only 1/18 and 1/15 of the SPSW and BRSW systems on average respectively. The PBRSW system with vertical arrangement of the composite shear wall modules shows the best mechanical behavior with the highest bearing capacity and energy dissipation among the three assembly arrangements. Experimental data coincides well with those from finite element model (FEM) analysis and therefore validates FEM.

三种装配方式的预制屈曲约束复合剪力墙体系的抗震性能研究

预制建筑在实现可持续城市化中起着重要作用,因此引起了全世界的关注。在这项研究中,开发了一种预制屈曲约束复合剪力墙(PBRSW)系统,该系统由现场的多个复合剪力墙模块组装而成。比较设计和研究了具有复合剪力墙模块的三个装配布置(垂直,水平和交叉布置)的PBRSW系统,以减轻屈曲现象并通过实验和仿真方法获得有益的机械性能。为了深入了解已开发系统的抗震性能,进一步研究了传统的屈曲约束剪力墙(BRSW)系统和钢板剪力墙(SPSW)系统。结果表明,PBRSW系统具有丰满的磁滞行为,与其他两个系统相比,具有更高的承受力和能量消耗能力,以及更好的延展性能。有效地消除了PBRSW系统的屈曲现象,其最大平面外位移平均分别仅为SPSW和BRSW系统的1/18和1/15。垂直布置复合剪力墙模块的PBRSW系统在三种装配布置中表现出最佳的机械性能,具有最高的承载能力和能量耗散。实验数据与有限元模型(FEM)分析的数据非常吻合,因此验证了FEM。其最大平面外位移平均分别仅为SPSW和BRSW系统的1/18和1/15。垂直布置复合剪力墙模块的PBRSW系统在三种装配布置中表现出最佳的机械性能,具有最高的承载能力和能量耗散。实验数据与有限元模型(FEM)分析的数据非常吻合,因此验证了FEM。其最大平面外位移平均分别仅为SPSW和BRSW系统的1/18和1/15。垂直布置复合剪力墙模块的PBRSW系统在三种装配布置中表现出最佳的机械性能,具有最高的承载能力和能量耗散。实验数据与有限元模型(FEM)分析的数据非常吻合,因此验证了FEM。
