Hysteresis Analysis on Beam-Column Connection of Concrete-Filled Steel Tubular Structure under Cyclic Loading

Abstract:

The concrete-filled steel tubular structure is widely used in practices, as it shows perfect seismic performances such as ductility, and has strong ability of collapse under seismic loading. In this paper, firstly, the stiffness damage and stiffness recovery parameters of concrete constitute model under cyclic loading was calibrated and verified by examples. Then the finite element model was verified by numerical examples of reinforce concrete members and concrete-filled steel tubular members. At last, on the base of the result of analysis and verification, the hysteresis curves on beam-column connection of concrete-filled steel tubular structure under cyclic loading were simulated and compared with experimental results, and the hysteresis characters was analyzed in the end.
