Abstract

A seismic isolator includes a slider, and a path with non-fixed curvature; the path is positioned on a base; the slider is placed on the path, and bears the weight of a super-structure; the path with non-fixed curvature can be a smoothly curved surface; a layer of ductile material with high compressibility is mounted between the slider and the path with non-fixed curvature; therefore, when an earthquake occurs, the slider will slide on the path with non-fixed curvature to produce vibration isolation effect for the superstructure; loading capacity of the isolator increases, and resonance between the isolator and low-frequency earthquakes is prevented.
