【Abstract】 Shaking table tests on a model of composite isolation structure were performed.By adjusting the number of the elastic sliding bearings in the isolation layer,the influences of the change of friction bearing ratio on the shear coefficient of the model,displacement response and frequency spectrum characteristics were studied.The experimental results show that the composite isolation system has good performance when the number of elastic sliding bearings is moderate and the friction bearing ratio is reasonable.更多还原
