Comparison of techniques for damage identification based on influence line approach

Nondestructive damage identification is an important sub-problem of a damage assessment. In the paper the techniques for damage identification based on displacement influence lines and its derivatives for undamaged and damaged beam structure has been outlined. These techniques can be used for damage identification for both the simply supported and the continuous beams. The damage identification efficiency is investigated through techniques based on displacement influence lines is investigated. The numerical studies and experimental verification of the techniques have been carried out. The change in the rotation of displacement influence lines is generally the most reliable indicator for damage location.
