SI기법에 의한 구조물 손상진단

초록

Concept of SI(system identification) is explained as an inverse problem. SI methods are classified by model-based and non-model-based algorithms. Depending on the type of measured response, static, frequency-domain, and time-domain SI methods are introduced. Issues related to each algorithm are discussed and their advantages are compared. The applications of SI methods for structural damage assessment are briefly reviewed through simulation studies.
