This study investigates earthquake response characteristics of a high-rise reinforced concrete building constructed within the damage belt of Kobe City during the 1995 Kobe earthquake. Weak nonlinearity is inferred from the top and base records of the building during the 2000 Tottori-ken Seibu earthquake. After dynamic parameters of the building are tuned up, the records in the building are well simulated in nonlinear earthquake response analyses. Then, the ground motions in the neighboring area are evaluated taking into account the deep subsurface structure. The seismograms obtained at GL-300m beneath the building and at the mountain area are well simulated from records on ground surface adjacent to the building. Finally, the effects of the deep subsurface structure on the seismic response of the building are studied, which is not negligible because of ground motion amplification in the basin-edge structure.
