부분강접 T-sutb 접합으로 조립된 CFT 합성골조의 실험적 모드해석

초록

In this study experimental vibration tests are performed on CFT composite frame with T-stub connections using experimental modal analysis techniques. Using experimental modal analysis techniques, the modal parameters of the CFT composite frames yielded by the modal testing of the vibration exciter are compared and investigated with the natural frequencies and mode shapes obtained by finite element analysis. In this paper the basic database is provided to evaluate damage, which can be determined based on the changes in the element properties, resulting from the process of updating the finite element model benchmark and experimental data.
