Abstract：In this paper, for the slide-limited friction base isolation technology, the total restoring force model of the isolation device is given, the motion equation of the isolation system is established, and the nonlinear analysis program is worked out. The influence factors such as friction coefficient, elastic stiffness and yield displacement of the displacement-constraint device on the base isolation system are analyzed in detail, and based on a great deal of analysis, the rational range of the parameters are given, which can provide reference for design and application of the friction base isolation system.
