摘要：
Low cyclic loading tests were carried out on one bare reinforced RC frame, one masonry-infilled RC frame and three composite filled wallboard RC frames with different connection modes to investigate the effects of prefabricated composite infilled wallboard with different connection modes on the seismic behavior of RC frame structures. It can be divided into rigid connection, semi flexible connection and flexible connection according to different connection modes. Through the test, the effects of infilled wallboard on the bearing capacity, stiffness, ductility and energy dissipation capacity of the frame were analyzed. The following conclusions can be drawn that the composite infilled wallboard with rigid connection will increase the lateral stiffness and horizontal bearing capacity of the RC frame greatly, while the ductility will become poor. The lateral stiffness and horizontal bearing capacity of composite infilled wallboard RC frame with flexible connection and semi flexible connection are higher than that of the RC frame with block infilled wall, and the ductility is better than that of RC frame with block infilled wall. During the loading process of the RC frame with composite wallboard infilled with semi flexible connection, the wallboard and frame are destroyed successively, showing good energy dissipation capacity. It is suggested that flexible connection or semi flexible connection should be adopted between the infilled wall and the frame in engineering application. © 2020, Editorial Office of Journal of Building Structures.
