A novel and efficient method is presented for identifying the location and severity of damage in structural elements using vibration modes and circular natural frequency. This method is based on sensitivity analysis of the structure and allows for model updating of a given structural finite element construct using the iterative process of the Levenberg–Marquardt algorithm. The proposed approach is superior in its capability of locating and estimating the severity of structural damage in the presence of noise or incomplete response. The efficiency and performance of the proposed method are assessed through numerical case studies.
