Zusammenfassung:The new research center for Earth-Life Science Institute / Tokyo Institute of Technology is designed with three-stories concrete structure whose first story has very high horizontal stiffness and strength with heavy seismic walls, while upper two stories are composed of flexible moment frames without enough seismic walls to obtain the architectural flexibility against various program. To ensure the seismic performance of upper structures in this building, the walls around the stairs and soft moment frames are separated and energy-dissipating fuses are installed in between. In this paper, the seismic performance of the proposed system is researched, and the optimal design of the fuses is discussed.
