Damage and Peak Shear Strength of Low-Aspect-Ratio Reinforced Concrete Shear Walls
Publication: Journal of Structural Engineering
Volume 145, Issue 11
Abstract
Engineers inspecting damaged buildings after an earthquake are tasked with determining whether the lateral stiffness and strength of the building has been compromised, including whether the displacement associated with peak shear force of the building has been reached or exceeded. For buildings constructed with low-aspect-ratio reinforced concrete shear walls, a structural repair may not be necessary if the earthquake-induced displacement of the wall is less than the displacement associated with peak shear force. However, there are no quantitative data in the archival literature or technical reports that enable an engineer to determine whether the displacement associated with peak shear force has been reached based on postearthquake observations of damage, including crack widths and lengths, and spalled concrete. This paper documents damage to low-aspect-ratio shear walls at peak transient displacements and subsequent displacements at zero lateral loading and enables decisions to be made regarding whether peak shear force has been attained. Ratios of crack width at peak transient displacement and subsequent displacement at zero lateral loading (the postearthquake condition) are provided to assist with the postearthquake evaluation of damaged buildings.
