Abstract Aiming at the problems of precast (bhu RC) beam-column joint connection and repair after earthquake damage, a repairable connection form of beam-column joint is proposed. In order to verify its effectiveness and feasibility, a full-scale precast joint specimen was designed and tested under quasi-static loading, and the test results were compared with those of cast-in-place joint specimen. The results show that the bearing capacity, ductility, deformation and energy dissipation capacity of the precast joint are significantly better than those of the cast-in-place joint, and the damage is mainly concentrated on the multi-slit energy dissipation device, and the precast beam and column members are basically in the elastic stage, which can realize the purpose of joint damage control and rapid repair after earthquake. On this basis, a simplified numerical model of the precast beam-column joint and structure is established, and the seismic performance of this kind of prefabricated RC frame structure is studied by nonlinear dynamic time-history analysis. The results show that the fabricated structure performs well under all levels of horizontal earthquake, meets the requirements of seismic code design, and its overall seismic performance is basically close to that of cast-in-place structure.
