REGIONAL DIFFERENCES OF LOSS RATIO OF BUILDING DAMAGES CAUSED BY LONG PERIOD STRONG MOTIONS

–Loss prediction during huge Nankai trough earthquake–

Abstract

This paper presents a technique to evaluate regional differences of loss ratio of building damages caused by long period strong motions. Loss estimation is important, since the impact of building loss on the business must be evaluated to construct business continuity plan. Loss ratio of model buildings are calculated by 3D elasto-plastic response analyses using long period strong motions in consideration of response spectra variations. Regional differences of two kinds of high-rise buildings have been analyzed against huge Nankai trough earthquake. The proposed technique has revealed regional differences in the magnitude and the type of building loss, and the measures.
