In this study, the authors investigated the behavior of the proposed bolt-assembled precast panel building (BPPB) system under the simulated seismic loading through a large experimental campaign. A pseudo-static test was carried out on a two-story half-scale building specimen constructed by many individual precast components which were properly joined together with bolted connections. The results show that the building specimen had the good seismic performance with high bearing capacity, comparable energy dissipation capacity and perfect structural integrity. The crack pattern and failure mode of the building specimen are different from those of traditional cast-in-situ concrete structures and equivalent cast-in-situ precast concrete structures. The final damage was concentrated in the bolted joint zones, a shear failure occurred in the edge of concrete panel near the bolt holes. It results in that the traditional design approaches of concrete shear wall cannot be applied to this new system. Therefore, the design philosophy and design formulas were proposed for the bolt-connected precast concrete panels to ensure the ductility of the panels and further improving the seismic performance of the BPPB system. The design theory of the bolt-connected precast concrete panels was validated by the successful prediction of the building specimen’s flexural capacity.

一种新型螺栓组装预制板建筑结构的抗震性能试验研究

在这项研究中，作者通过大型实验活动研究了所提议的螺栓组装预制板建筑 (BPPB) 系统在模拟地震载荷下的行为。对一个由许多单独的预制构件构成的两层半比例建筑样本进行了伪静态试验，这些预制构件通过螺栓连接正确连接在一起。结果表明，该建筑试件具有良好的抗震性能，承载力高，耗能能力相当，结构完整性好。建筑试件的裂缝模式和破坏模式不同于传统的现浇混凝土结构和等效的现浇预制混凝土结构。最终损坏集中在螺栓连接区域，在螺栓孔附近的混凝土面板边缘发生剪切破坏。这导致传统的混凝土剪力墙设计方法无法应用于这种新系统。因此，提出了螺栓连接预制混凝土板的设计理念和设计公式，以保证板的延性，进一步提高BPPB系统的抗震性能。通过成功预测建筑试件的抗弯承载力，验证了螺栓连接预制混凝土板的设计理论。提出了螺栓连接预制混凝土板的设计理念和设计公式，以保证板的延展性，进一步提高BPPB系统的抗震性能。通过成功预测建筑试件的抗弯承载力，验证了螺栓连接预制混凝土板的设计理论。提出了螺栓连接预制混凝土板的设计理念和设计公式，以保证板的延展性，进一步提高BPPB系统的抗震性能。通过成功预测建筑试件的抗弯承载力，验证了螺栓连接预制混凝土板的设计理论。
