Experimental and Numerical Verification of a Sloped Sliding-Type Isolation System

Experimental and Numerical Verification of a Sloped Sliding-Type Isolation System

In recent years, seismic isolation technology has been widely applied in the construction of buildings and bridges. Various kinds of new isolation technologies have been proposed to satisfy different demands. This article introduces an innovative seismic isolation system called a sloped sliding-type bearing. First, the nonlinear equation of motion is derived. Then, the numerical simulation method is established. Finally, the simulation results are verified through shaking table tests. Numerical and experimental results show that the isolation system is effective against a real earthquake. The isolated acceleration response is well controlled by the friction coefficient and the slope of the sliding surface.
