Note (General): An isolation system can significantly reduce the deformation of the superstructure by focusing the deformation on the isolation layer. When friction pendulum bearings (FPBs) are applied, this deformation will be highly related to the friction coefficient. Therefore, the influence of the friction dependencies on the maximum displacement is of vital importance. However, the reliability of proposed friction dependencies under real earthquakes and the effect of friction dependencies on the maximum response displacement remain unclear. Thus, the friction dependencies were combined in friction models and further validated by full-scale dynamic tests under unidirectional and bidirectional orbits. Further, the contribution of friction dependencies to the maximum displacement and superstructure acceleration was assessed under various earthquake excitations and various base isolation systems.
