In this paper, we study the influence of ground motion predicted for Uemachi Faults to the response of highrise buildings. Two highrise buildings were modeled to fishbone-shaped frame model and time-history analysis was performed. Then, we compared response of fishbone-shaped frame model with response of other vibration models.Also, we studied the influence of PΔ effect. As a result, the following conclusions are obtained. 1) The response to the predicted ground motion is much larger than that of the seismic design motions. 2) It tends to evaluate the response small in a more detailed vibration model. 3) When the first mode response is predominant, the influence of PΔ effect is large.
