Design of Huge Complex Building of Two Structurally Independent Seismic Isolation Structures Coupled by Unique Expansion Joint

摘要

For large-scale complex facilities, the authors designed seismic isolation structures which were ensured the highest-level safety in a rational and economic way. We split the building into two first, and then planned the buildings so that their spans and story heights might be optimum according to their uses, and performed the structural design of each building in pursuit of rationality and economic efficiency as well as safety. Finally, the buildings were integrated into one by connecting the two seismic isolation buildings with special expansion joint which was developed for these buildings. Additionally, we considered long-period earthquakes and strong inland earthquakes that were larger than the reference earthquake of the Japanese Building Codes to ensure highest-level aseismic performance.
