Behaviour of self-centring shear walls——A state of the art review

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.
