Abstract
In this study, wind response properties of high damping laminated rubber bearings (HDR) is investigated by experimental and analytical methods. According to the experimental result of HDR, horizontal creep deformation depends on magnitude of dynamic loading as well as that of static loading under the wind loading. This feature differs from other seismic isolation devices. Then we propose the simplified evaluation method and hysteresis model for time history response analysis under wind loading, which are established by taking account of the effect of creep deformation caused by dynamic loading. Firstly, we perform the wind loading test for high damping laminated rubber bearings and establish the simplified evaluation method and hysteresis model based on the test results. Next, we verify the validity of proposed models by comparing the analysis results with experimental results. Finally, we perform the time history response analysis using proposed hysteresis model.
