Paper Abstract

Determination of damage location and severity are important for the arch structure. First, the frequency perturbation formulate in damage identification are derived combining matrix perturbation theory with finite element technology. Next, an experimental test was carried out to determine the first six frequencies in the intact and damage arch structure. Finally, the location and severity of structural damages can be detected based on the measured natural frequencies of damage structure. The result shows the frequency perturbation method is feasible to the structural damage detection for the only need of frequency-data, and can be applied to damage detection in the arch structure.
