BUILDING RESPONSE TO GROUND MOTION PREDICTED FOR UEMACHI FAULTS

Abstract

The objective of this paper is to evaluate the influence of ground motion predicted for Uemachi Faults to the response of buildings. Time history response analysis was performed on SDOF system equivalent to 5-story to 50-story buildings. Then, we compared response of the equivalent SDOF system with that of the MDOF system. As a result, the following conclusions are obtained. 1) The seismic motion characteristic changes depending on the strong motion prediction techniques, and so does the number of building stories with especially large response. 2) Most of the response to the predicted ground motion is larger than that to the seismic design motions, but it is the same level as that to the observed motions. 3) The maximum response of the MDOF system is larger than that of the equivalent SDOF system.
