Seismic Performance and Optimization of a Novel Partial Seismic Isolation System for Frame Structures

To improve the safety performance of important rooms, such as operating rooms and disaster command centers, during an earthquake, a novel partial seismic isolation system suitable for new existing frame structures is proposed, optimization analysis carried out. Using finite element numerical simulation method, models ordinary structure isolated were established. Considering response room, design impact on overall structure, this study analyzed damping effect system. We changed type bearing, location load to further optimize calculation structure. The results show that could significantly reduce room under action magnitude-8 rare earthquake. rate relative acceleration displacement between top bottom columns reach 90%. It was found proposed in paper applicable reinforced concrete without affecting main building. This easy construct, both structures, provides effective mitigation measure locally
