摘要：
The static Pushover analysis method is adopted to study the seismic performance of reinforced concrete frames with energy dissipating self-centering hinge joint (EDSC-HJ). Firstly,the structure of EDSC-HJ frame is introduced,and the finite element model of EDSC-HJ frame structure is established,and the correctness of the numerical simulation is verified by comparing with the shaking table test results. Secondly,the Pushover method is employed to assess the seismic performance of EDSC-HJ frame both with and without dampers and determine the mechanical parameters of the joint elastic force-restoring device and the energy-dissipating device. The results indicate that the reasonable range of relative rotational stiffness ratio of beam-column nodes of the EDSC-HJ frame is 0. 05-0. 5;the interlayer displacement responses of the EDSC-HJ frame with dampers decrease by 76% and meet the limit requirements;the base shear responses of the EDSC-HJ frame with dampers increase by 23% due to the additional lateral stiffness of the structure increased by the setting of dampers. The seismic performance of EDSC-HJ frame is obviously better than that of reinforced concrete frame (RCF)structure,and it has good toughness structure characteristics. © 2024 Southeast University.
