Experimental research and analytical theory for calculating the shear strength of squat reinforced concrete walls
Abstract
The aim of this thesis is to develop a theory that realistically captures the mechanism of shear failure in short walls with a shear-span to active length of the cross-section ratio (α/d = M/Vd) of 1-2.5 and that can be used to accurately calculate their shear strength. In the experimental part of the thesis, the shear strength of 16 short earthquake walls which were reinforced with various ratios of reinforcements along the wall and at the built-in end supports and stressed to failure by applying a monotonic shear force with or without an axial compressive load was examined. A specific loading arrangement reproduced the stress state of the walls of a structure. The experimental programme examined the impact of the following basic parameters on the shear strength of short walls: the value of the axial compressive force, the distributed longitudinal and transverse reinforcement of the web, the longitudinal reinforcement of the confined end zones, the compression strength of the concrete ...
