Mitigation of earthquake hazards using seismic isolation systems

摘要

This paper describes mitigation of earthquake hazards using seismic base isolation systems. A numerical algorithm for analyzing system response of base-isolated structures with laminated elastomer bearings is briefly described. Seismic response analyses of both base-isolated and unisolated buildings under earthquakes no. 42 and no. 44 are performed and the results are compared to illustrate the mitigating effect of base-isolated systems.
