시나리오 지진 기반 구조물의 지진위험지도 구축 방법

Abstract

Since digital instrumental recording was started by the Korean Metrological Administration (KMA) in 1999, the 2016 Gyeongju earthquake and 2017 Pohang earthquake were two largest earthquakes, causing noticeable damage of building structures damage and human casualties. In this study, ground motions are generated by stochastic simulation based on the point source model for the scenario earthquakes in tthe Korean peninsula. Nonlinear response history analyses are conducted using a three-story gravity-designed reinforced concrete (RC) frame located at a site with different epicentral distances. Seismic risk contour maps associated with a RC building are constructed for potential scenario earthquakes occurred at the epicenters.
