SEISMIC RESPONSE EVALUATION METHOD FOR MAXIMUM RESPONSE AND CUMULATIVE DAMAGE OF HIGH-RISE BUILDING UNDER THE TOKAI-TONANKAI-NANKAI MULTI-SEGMENT EARTHQUAKE BASED ON THE RESPONSE OF THE EARTHQUAKES CONSTITUTING THE MULTI-SEGMENT EARTHQUAKE

Abstract

 This paper examines relationship between Tokai-Tonankai-Nankai multi-segment earthquake and the earthquakes constituting it in the responses spectra and the energy spectra. Based on these relationships in the spectra, this paper proposes a seismic response evaluation method for maximum response and cumulative damage to Tokai-Tonankai-Nankai multi-segment earthquake of high-rise building. The maximum response is estimated by increasing the single ground motion to the level of the multi-segment earthquake before seismic response analysis. The cumulative damage is estimated by using energy balance. The proposed evaluation method is validated by comparing its results with those of seismic response analysis.
