Abstract

 Uplifting Slide Shoe (so called UPSS) is a slide bearing consisting of a horizontal plane and two inclined planes. The restoring force of UPSS is caused by the gravitational potential energy. The original time-history characteristics are uniquely determined by the slope angle.<br> In this paper, the predominant period of UPSS is evaluated in comparison with rubber bearings and isolation bearings. One method is utilizing the natural period based on the maximum displacement and the associated restoring force. Others are Fourier transform and wavelet transform. As a result, the predominant periods obtained by Fourier transform and Wavelet transform spread over a wide range of period, and those are almost consistent. Furthermore, by comparing the time history response results, the change of the predominant period along the time axis has become clear in the wavelet transform result.
