"A global damage detection algorithm for bridge-like structures is proposed. This method provides the capability of determining the reduction in both stiffness and damping parameters of the structural elements. It is assumed the mass of the structural elements is not affected by the damages, which is a reasonable assumption for bridge-like structures. The proposed method uses the state space representation of the structural dynamics to make the diagnosis of the structural integrity. Given that the state space representation of any system is not unique, the damage detection procedure is developed for the physical coordinates of the state space representation. A transformation method to get any arbitrary state space representation into the physical coordinates is also developed.
The feasibility of the proposed damage detection algorithm is verified on a numerical example as well as on a simulated three-bar truss structure with three degrees-of-freedom"--Abstract, page iii.
