Has been widely applied in order to minimize damage such as earthquake engineering and building structures, because the economics and efficiency is relatively good seismic isolators. Are widely used from the seismic isolation bearings LRB inhibits excessive displacement occurs on foot by improving the damping capacity of the seismic isolation structure with the flexibility of the rubber bearings during the earthquake, and secure the safety by reducing the seismic forces.
The flexible backing is required unlike the conventional one for civil engineering, considering the characteristics of the seismic isolation building plate is the upper structure. The aim of this study was to perform a compression and shear tests to validate the performance limits of the performance of seismic isolation bearings supporting the main features of the structure and lateral displacement.
