Research on Coordination Relationship Between Energy Dissipation and Recentering Capacities of Self-centering Beam-Column Joints
The purpose of this study is to investigate the coordinated relationship between energy dissipation and recentering capacity of Self-Centering Beam-Column Joints(SCBCJs),and propose a simplified design method to achieve rational configuration of energy dissipaters and prestressing tendons in SCBCJs.A theoretical restoring force model of SCBCJs is established to explore the coordinated relationship between recentering and energy dissipation capacities of such joints.The feasibility of the simplified design method is verified through finite element analysis.The energy dissipation capacity of the joint increases with the increase of the recentering-to-dissipation ratio R,while the recentering capacity decreases with the increase of R.Under cyclic loading,the hysteresis loop of SCBCJs exhibits a"flag"shape with no residual deformation,indicating strong energy dissipation capacity.The established expression of the coordinated relationship can characterize the energy dissipation and recentering capacities of SCBCJs.The proposed simplified design method achieves rational matching of energy dissipation and recentering capacities in SCBCJs,thereby addressing the issue of energy dissipater and prestressing bar allocation during design.
