Abstract
To solve the structural damage identification problem, this paper proposed a damage identification method with a single-node mode shape parameter βASS by adopting the additional mass method and mode shape parameters. This index method moves the additional mass as a constant force on the same cross-section beam structure, and extracts the mode shape parameters of the structure at a fixed point, with operation simplification conducted to accurately identify the damage location and different damage parameters of the same section beam structure by utilizing only the single-node mode shape parameters. The identification accuracy is high when the additional mass accounts for about 5% of the total beam mass and is close to one end of the fixed hinge support. In the proposed identification method, only single-node mode shape parameters on the beam structure are needed to determine the damage location, which has certain engineering application significance for damage detection of beam structures with the same cross-section.
