Damage Detection based on Single-Input-Single-Output Measurements
Publication: Journal of Engineering Mechanics
Volume 129, Issue 2
Abstract
A methodology is presented for detecting damage of structural systems maintaining a linear response. A single frequency response function measured at several frequencies along with a correlated analytical model of the undamaged structure are used to detect and assess damage. The method is directed toward situations where the number of damaged elements is generally known to be limited. A computationally efficient method of recalculating a single receptance is presented. Numerical results for a two-dimensional structural frame are presented to validate and assess the proposed approach. Issues for the development of the approach are discussed.
