Abstract

This paper uses a damage detection approach based on dereverberated transfer functions. In 1D structures, conventional reverberated transfer functions are formed because of the interactions between incident and reflected waves in structures. By applying virtual controllers to eliminate wave reflections, dereverberated transfer functions can be obtained. Dereverberated transfer functions provide good representation of a structure's local dynamics. Because local dynamics are more sensitive to parameter changes, the dereverberated transfer function appears to be suitable to infer structural damage. In this study, a three- story building model is tested under seismic wave excitation. Experimental results show that this approach can be used to locate damage, determine damage type, and quantify damage extent.
