The hysteretic behavior of High Damping Rubber (HDR) bearings is significantly affected by inner temperature and hysteresis self-heating interactions, the stiffness of HDR is increased at lower inner temperature. To introduce the HDR bearings in cold earthquake prone regions, a temperature- dependent hysteresis model is of great concern. In this study, a thermo-mechanical coupled model is proposed for HDR bearings. The model parameters are identified from quasi-static loading tests at ambient temperatures of 23°C, 0°C and −20°C, and the validity of the model is discussed based on a comparison of the numerical seismic response of a bridge model using HDR bearings with the hybrid simulation result at 23°C, 0°C and −20°C. An acceptable agreement can be observed between the model and test result at the 23°C and 0°C under seismic loading conditions. |
