최적화기법을 응용한 주파수영역에서의 구조물 손상도 추정에 관한 연구(2) -모형의 검증-

초록

A total of 3 models based on Hassiotis (1993) and the accompanying paper (Lee, et al., 2002) have been con-sidered, both numerically and experimentally, to verify the applicability and advantage/disadvantage of the mod-els. Numerical results indicated that the proposed models by Lee, et al. are useful to the continuous beam as well as to the simple beam, whereas the Hassiotis model was not successful except cantilever beam structures. Moreover, the proposed model based on the homogenized crack concept showed good agreement with the numerical experiment when the damages are getting serious. Experimental results also show the similar pattern and the proposed model 3 is superior to the model 2 as the measurement noise are significant. Future works will be focused on the refinement of the damage detection model and the application to the concrete structures will also be investigated.
