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 structuresAccording to the energy release principle, the strain energy of a damaged element suddenly changes whenTherefore, the change in the static shear energy is employed to determine the damage locations in beam-likeThe static shear energy is derived from the spectral factorization of the elementary stiffness matrixThe advantage of using shear energy as opposed to total energy is that only a few deflection data points

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 1,   Pages 53-77 doi: 10.1007/s11709-022-0850-0

Abstract: post-tensioning (PT) in structural walls has led to the development of advanced self-centring (rocking) shearextensive research since the 1980s, there are no well-established design guidelines available on the shearsliding, confinement, seismic performance factors, PT loss, PT force range and residual drifts of shearThe established database was then used to review shear walls’ configurations, material, and componentsThe behaviour of concrete, masonry and timber shear walls were compared and critically analysed.
