  author={Dionisio Bernal},
Robust algorithms to construct minimum order state-space realizations from input/output data have been developed in the past two decades. Extracting the flexibility matrix at the sensor coordinates from the matrices of the realizations is of interest in damage detection applications. The operation requires 1) extraction of the undamped modes at the sensor coordinates and 2) a technique to obtain constants that permit the normalization of these modes with respect to mass. This paper reviews the… CONTINUE READING
