*Kosei Kawamata1, Sunghyon Jang1, Munemichi Kawaguchi1, Kazuhiro Sawa1, Shuhei Matsunaka2, Hideo Machida2 (1. Hokkaido Univ., 2. TEPSYS)

Keywords:Bayesian Theorem, Seismic response analysis, Seismic damage

原子力分野で地震解析に用いられている多質点構造解析を行い、正常時の地震応答データと損傷があるときの地震応答データを比較し、ベイズ推定を行うことで、構造物の異常検知、損傷箇所特定、損傷程度の推定を行う手法を構築することを目指す。
