For this purpose, a hybrid seismic response experiment for a bridge system is conducted and the hybrid seismic test results are further discussed with the aid of a numerical analysis. In the experiment, a steel pin bearing specimen is prepared. Numerical model applied in the experiment is a two-degrees-of-freedom model. A slip-type hysteresis is experimentally identified for the longitudinal and transverse directions, respectively. In this respect, a slip mode as well as a stiffness increase is observed arising from existence of space around the pin. In addition, the degree of superstructure response is affected by a slip-type hysteresis, particularly in the longitudinal direction. In the analysis, a numerical model for the steel pin bearing is developed based on the slip-type hysteresis characteristics. Then, the response of a bridge with the aid of the devised steel pin bearing is examined. As a result, the devised numerical steel pin bearing model can well assess global bridge responses associated with nonlinear bearing performance observed in the experiment. In addition, the pier ductility factor as well as the degree of superstructure response is clearly affected by the slip-type hysteresis.
