Detecting multiple damage types/locations in a civil building structure model
This paper uses a damage detection approach based on de- reverberated transfer functions to detect multiple damage locations in a building structure model. De-reverberated transfer functions (DTFs) can be obtained by applying virtual wave controllers to eliminate wave reflections at structural discontinuities and boundaries. The ratio of DTFs between two successive degrees of freedoms (DOFs) represents local structural dynamics. Multiple damage locations in a structure result in phase differences of DTFs before and after damage. Damage occurring in multiple locations can be determined by introducing the concept of phase damage index. However, one can identify multiple damage locations one by one along the traveling wave path. The downstream damage is identified and corrected until all damage elements are repaired. In this study, a three-story building model is tested under sine sweep wave excitation. Experimental results show that this approach can be used to locate the presence, determine the type, and quantify the extent of multiple damage conditions in a structure.
