説明

 Although rubber bearings are popular for seismic isolation bearings in Japan, Spherical Sliding Bearings (SSB) or Friction Pendulum Bearings (FPB) are also widely used in many countries including U. S. In this paper, shaking table tests on braced frame supported by SSB are carried out, and their dependency on pressure and velocity is examined. Also tests with the eccentric dead loads are conduted, in order to capture lift-up actions at bearings and their performance. Analytical models taking pressure and velocity dependency into accounts are proposed, and their validity against the experimental results are discussed.
