Extended Accumulated SIBIE in order to improve the limit of visibility of Accumulated SIBIE method is a method to significantly improve the performance of measurements by extension the region of visibility to a low-frequency region. Decrease of resonant frequency displayed in the lower frequency region than the thickness frequency is due to reduction in rigidity by essentially degradation and cross-sectional loss of members. It is necessary to clarify the relationship between the resonance frequency and the deterioration or damage patterns to learn these patterns. In this research, by obtaining the vibration mode and the natural frequency by the eigenvalue analysis, it was confirmed that dynamic analysis which take time and effort can be minimized.
