Abstract

In this paper, the model tests of 7 degree frequent earthquake, 7 degree fortification earthquake and 7 degree rarely met earthquake are carried out by using the seismic ground motion parameters of a design reference period of 60 years. Displacement of platen and columns, restoring force of foundation and reinforcement strain are obtained, as well as the position and development of cracks. The research shows that the spring vibration isolation foundation has good working performance under earthquake, and the vibration springs has certain effect of decreasing vibration.
