Abstract

Abstract

A structural damage identification technique based on wavelet transform of spatial structural response measurements is discussed. The two different boundary conditions considered are simply supported and fixed end support, and the different damage forms (crack characteristics) are investigated by numerical experiments. The results of the simulation show that boundary conditions have some effect on bridge damage detection, but the damage forms have no effect on it. All in all, if a suitable wavelet is selected, the method is capable to extract damage information from the response signal in a simple and reliable way.
