In order to detect damage the proposed method uses as data the modal shapes and vibration frequencies of the structures. The severity of the damage is measured in terms of the changes of stiffness of the structural elements. In order to do it, the method uses the analytical model of the structure to represent its initial state without damage. The modal shapes and vibration frequencies of the damaged state of the structure are used to fit their lateral stiffness matrix. Whit this matrix and by using an iterative process, the damaged elements of the structure are detected. Application of the method is illustrated evaluating different damage states of building models. Additionally, the effect of incomplete modal information is evaluated and discussed.
