Experiment Test and Numerical Simulation of Cable-Sliding Friction Aseismic Bearing with Buffer

By adding cable devices to common Pot bearings or Steel ball bearings creatively, cable sliding friction aseismic bearings (CSFAB) could not only have the advantages of sliding friction isolation bearings, but also overcome the defect of the sliding friction isolation bearings, which could avoid the unseating of girder during earthquake. Further development of CSFAB is proposed in this paper, by adding "cable-spring" system to conventional CSFAB. This new type of CSFAB is referred to as CSFAB with buffer. The feasibility of the CSFAB with buffer is verified by prototype of the bearing and corresponding pseudo-static test. The actual performance of the bearing is in good agreement with the theoretical model.
