    • PURPOSE: A wholesomeness evaluating system based on an auto regressive model of a foundation-structure interface of harbor caisson is provided to rapidly and effectively perform a safety inspection of a harbor caisson structure. CONSTITUTION: A wholesomeness evaluating system based on an auto regressive model of a foundation-structure interface of harbor caisson distinguishes damages of a foundation-structure interface with signals measured from a structure. Signals in a time area contains more information relatively to data of a frequency area or a mode area. An auto regressive model is used for analyzing vibration signals. The Mahalanobis' square distance is used for an outlier analysis of signal properties of the time area analyzed with the auto regressive model/ The existence of the damage is determined by using a result of the outlier analysis.

    • PURPOSE: A two-stage acceleration exploration technique for performing safety evaluation for a harbor caisson structure is provided to perform precise and safe diagnosis only if there is a doubt on the safety of a structure by dividing a measurement system for a safety evaluation. CONSTITUTION: After the dynamic characteristics about the entire harbor structure are rapidly evaluated using an equipment for applying the same excitation to the same location, a structure which has relatively many damages is discovered. The equipment comprises a GPS(Global Positioning System) and an excitation hammer for introducing the same excitation. The dynamic characteristics are evaluated using the natural frequency or the correlative coefficient of a frequency response function. A lot of sensors are attached to the structure having many damages and a compulsory vibration test is performed using a ship. The natural frequency and the local mode shape are extracted from the signal obtained from the compulsory vibration test and the particular damage position and the damage degree are determined using the extracted information.
