A novel structural system based on precast reinforced concrete (RC) shear wall panels mutually connected vertically using T-connectors and horizontally using friction-bearing devices (FBDs) mounted on interposed steel columns was recently proposed. To investigate the seismic performance of the proposed precast RC shear wall system, three subassembly specimens simulating a single construction modulus were constructed and tested by considering different slot length and numbers of FBDs under quasi-static cyclic loading. Ductile flexural failure at drift of around 4.2% and load of around 265 kN was attained for both specimens with long-slot FBDs, while shear failure after moderate flexural ductility was attained at drift of around 3.8% and higher load of around 368.3 kN for specimens with short-slot FBDs, showing not-direct dependence of the load capacity on the number of FBDs installed. However, the higher number of FBDs allowed for higher hysteretic damping with a 27.3% increase in dissipated energy through cycles.

最近提出了一种基于预制钢筋混凝土 (RC) 剪力墙板的新型结构系统，该剪力墙板使用 T 型连接器垂直连接，使用安装在插入钢柱上的摩擦轴承装置 (FBD) 水平连接。为了研究所提出的预制钢筋混凝土剪力墙系统的抗震性能，在准静态循环载荷下，通过考虑不同的槽长和 FBD 数量，构建并测试了三个模拟单一结构模量的组件试件。对于具有长槽 FBD 的两种试样，在漂移约 4.2% 和载荷约 265 kN 时实现了韧性弯曲破坏，而在试样的漂移约 3.8% 和约 368.3 kN 的较高载荷下实现了中等弯曲延展性后的剪切破坏使用短槽 FBD，显示负载能力与安装的 FBD 数量的非直接相关性。然而，更多数量的 FBD 允许更高的滞后阻尼，通过循环耗散能量增加 27.3%。
