Abstract: A seismic response simulation method based on multiple-sping (MS) model and curve approximated hysteresis rules is proposed to predict nonlinear seismic response of steel bridge piers excited by bi-directional ground motions. A series of approximated curves and hysteretic rules are adopted to de-script the complicated nonlinear equivalent stress-strain relationship of spring elements in base of steel piers. An optimization calculation based parameters identification method is used to decide the six parameters of the constitutive relation from results of uni-directional cyclic loading tests. By comparing the results due to the simulation and pseudo-dynamic loading tests,the validity of the proposed method is also verified.
