EXPERIMENTAL VERIFICATION OF A STRUCTURAL DAMAGE DETECTION METHOD
An early detection of structural damage is important for structural health monitoring systems. Analysis techniques for damage tracking of structures, based on vibration data measured from sensors, have been studied recently without experimental verifications. In this paper, a newly proposed data analysis method, referred to as the adaptive quadratic sum squares error (AQSSE), for the damage tracking of structures will be verified experimentally. In the AQSSE approach, only a limited number of response data are needed. A series of shaking table tests using a small-scale 3-story building model have been conducted. In these experimental tests, different damage scenarios were simulated and tested to verify the capability of the proposed AQSSE approach in tracking the structural damage. The tracking results for the stiffness of all stories, based on the AQSSE approach and measured acceleration response data, are compared with the stiffness predicted by the finite-element method. Experimental results demonstrate that the AQSSE approach is capable of tracking the structural damage accurately.
