G1000904 A Study on Seismic Isolation System with Special Cross Railed Groove Method (Part II)

Abstract

The displacement and crossing angles changes in the S-curved grooves design, which increases the dampening performance. Under seismic vibration test, expected results were confirmed. Therefore, design optimization was conducted using theoretical analysis. Based on the analysis result, the response displacement was reduced to 14cm under JMA Kobe seismic wave 100%, which is smaller than traditional response displacement of 20cm.
