The purpose of this paper is to review and analyse previous research conducted on axially loaded Reinforced Concrete (RC) walls, with and without openings, supported on three sides. The test panels, with a slenderness ratio of 30, were subjected to a uniformly distributed axial load at an eccentricity of one sixth of the wall thickness. In this study, the effects of wall dimensions, concrete strengths and opening configurations are evaluated against the simplified wall design equation specified in the Australian Concrete Standard (AS3600-09) and other published test results. The behaviours of RC walls are also investigated by the Finite Element Method (FEM) using ABAQUS software. Experimental failure loads are compared to those obtained from the FEM in which a sound agreement is observed for high strength concrete walls. Some contradictory results between the FEM and experimental tests are also observed, particularly when the effects of different opening locations are investigated. The paper concludes by summarising the issues in previous studies and highlighting some areas where further investigations on RC walls, with three sides restrained, are required.
