Sažetak
In this paper the problem of using displacement influence lines to detect, locate and evaluate degree of damage in beam structures is investigated. The displacement influence line curvature enables locating the damaged section reliably. But the curvature method is not always reliable for damage evaluation. Changes in the displacement influence line curvatures are caused by changes in the bending moment and the bending stiffness. In static undetermined systems, theoretically, change in bending stiffness cause change in bending moment as well. Therefore, the strain energy method has been applied to evaluate rate of damage in the damaged section. The main advantage of the presented method is a need for only a few measuring points in the structure.
