Abstract

In order to study the influence of strengthening ring on the seismic performance of the recycled concrete filled steel tubular column and steel beam joints. In this paper, reinforcement ring, reinforcing ring extending length, thickness as the test parameters, a total of 4 recycled concrete filled square steel tubular columns and steel beam composite joints were designed and manufactured on this experiment. And the low cycle repeated load test is carried out to study the failure process and characteristics of this kind of joints, hysteretic curve, bearing capacity, ductility and so on. The results show that: strengthen ring can effectively limit the joint core area of steel pipe drum deformation, improve the joints seismic bearing capacity, deformation behavior and hysteretic curve of the full extent of the node; Weld quality has great influence on recycled concrete filled square steel tubular columns and steel beam composite joints. In a certain range, with the strengthening ring overhanging length increases, hysteresis curves are more full and the seismic bearing capacity will also increase, and the ductility coefficient will decrease, but reduced amplitude is relatively small; The thickness of the strengthening ring has little influence on the seismic performance of the joints.
