Abstract
In this study, a small laminated rubber bearing (LRB) using near-natural rubber is designed as a representative model of equipment seismic isolator to improve the seismic performance of the nuclear power plant (NPP). Some equipment of high safety importance is chosen to apply the seismic isolation using LRBs, and its design variables in consideration are reviewed to reduce seismic response. In comparison with the large LRBs for building structures, the control of design parameters for small LRBs, such as natural frequencies and shape factor, is very limited by the difficulties of fabrication. The paper discusses how they are updated and changed through the performance testing process.
