ESTIMATION OF STRONG GROUND MOTION USING KIK-NET RECORDS AND ITS APPLICATION FOR INVESTIGATION OF THE CAUSE OF STRUCTURE DAMAGE : A case study of electrical substation structure damage during the 2000 Tottori-ken-seibu earthquake

Abstract

In order to discuss applicability of strong motion simulation method by 1-D multiple reflection analysis using KiK-net records, we estimate strong motions at the substation where sustained transformer damage during The 2000 Tottori-ken-seibu earthquake. Estimated strong motions are utilize to simulate a dynamic response of soil-base-transformer system. In the substation, the one transformer located on cutting soil was damaged and the other one located on embankment was survived. Analytical results well explain the state of transformers during Tottori-ken-seibu earthquake. By using this method for strong motion simulation after great earthquake, it is possible to investigate the cause of structure damage.
