Structural Stiffness Estimation and Optimum Sensor location for Structural Damage Detection

구조물의 손상 탐지를 위한 시스템 축소 및 주자유도 선정과 강성도 평가

Damage detection is a very active research field, in which significant efforts have been invested in recent years. In this paper, analysis using structural stiffness estimation for damage detection is presented and compared to other methodologies. By using a cantilever analytical beam model, it is shown here that not only location but also the amount of damage in structure can be predicted from the ratio of change in stiffness. Damage detection experiment in real beam specimen on is also peformed and the results are compared.
