As the seismic isolation devices, 42 seismic isolation rubber bearings and 10 oil dampers are installed on the isolation floor. The structural robustness is reflected into the seismic criteria which can be achieved by the tube structure combined seismic isolation system with notably rigid superstructure utilizing RC core walls. Seismic criteria are categorized into two levels of earthquakes: Level 1 earthquakes and Level 2 earthquakes. Level 1 earthquakes are denoted as rarely occurred earthquakes with 50-year return period, which can occur several times in building service period. Level 2 earthquakes, on the other hand, are denoted as extremely rarely occurred earthquakes with 500-year return period, which can occur one time in building service period. To guarantee the high seismic resistant performances, all member stresses are supposed to be less than or equals to short-term allowable stresses and story drift is limited to less than 1/300 in the event of Level 2 earthquakes. Seismic performances of the building are evaluated based on nonlinear time history analyses using Multi-Degree-ofFreedom (MDF) model with bending and shear springs in each story and sway-rocking springs on the isolation floor. The 3D frame model for nonlinear static pushover analyses is composed simultaneously to evaluate the validity of analyses results based upon MDF model.
