EARTHQUAKE RESPONSE ANALYSIS OF RC HIGH-RISE BUILDINGS UNDER NANKAI TROUGH LONG-PERIOD EARTHQUAKE GROUND MOTION

Abstract

Responses of the reinforced concrete high-rise buildings under long period ground motions in case of the Nankai Trough large scale earthquake are calculated using the nonlinear three-dimensional frame analysis. In the analysis, slab contribution to the beam flexibility, slab behavior in the flexural hysteresis of a beam, and P-Delta effect are properly considered. From the analysis results, it was found that significant damage difficult to maintain their function may occur in the high-rise buildings.
