데이터 유사도 기반 구조건전성 모니터링 연구

Abstract

The main objective of this study is to develop a new damage detection method. The newly developed damage detection method uses data similarity of natural frequencies change ratios between non damaged structures and damaged structures. A cosine similarity is considered to estimate location and severity of the damages in the structure. Numerical validation was carried out to verify the performance of the proposed method. As a result, the damages in the structures is accurately detected.
