A passive energy-dissipating device,velocity,and displacement dependent hydraulic damper (VDHD),is developed to reduce the seismic response of structure.This device is cemprised of a hydraulic jack,check valve,relief valve,and throttle valve.The numerical analysis model for SAP2000 nonlinear analysis program is proposed to simulate the energy-dissipating characteristics of VDHD.The analysis re-sults of this model compared with the seismic resistant tests reveal that this proposed model can accurately describe the actual energy-dissipating behavior of VDHD.The efficiency of VDHD is confirmed using this proposed model for carrying out numerical analyses of bare building,building added with bulking resistant bracing(BBR),and VDHD.The energy-dissipating capabilities of VDHD are performing excellent displace-ment and acceleration control with various ground magnitudes;being an energy absorber to absorb me-chanical energy in the structure and resist structural movement;and gathering the advantage of BRB.
