Damage detection in beam-like structures using static shear energy redistribution

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 12,   Pages 1552-1564 doi: 10.1007/s11709-022-0903-4

Abstract: In this study, a static shear energy algorithm is presented for the damage assessment of beam-like structuresthe energy release principle, the strain energy of a damaged element suddenly changes when structural damageTherefore, the change in the static shear energy is employed to determine the damage locations in beam-likeis that only a few deflection data points of the beam structure are required during the process of damageAnother advantage of the proposed approach is that damage detection can be performed without establishing

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3,   Pages 722-730 doi: 10.1007/s11709-020-0624-5

Abstract: Strain Energy of the structure can be changed with the damage at the damage location.The accurate detection of the damage location using this index in a force system is dependent on thedegree of accuracy in determining the structure deformation function before and after damage.Then two damage detection indicators were developed based on strain energy variations.Damage was simulated by decreasing stiffness at different sections of the deck.
