Behavior of Axially Loaded Concrete Wall Panels with Openings: An Experimental Study

Forty seven reinforced concrete walls with various opening configurations are tested in both one-way and two-way action. The test panels, with a slenderness ratio of 30, 35 or 40, were subjected to a uniformly distributed axial load at an eccentricity of one sixth of the wall thickness (tw/6). Apart...

Description
Summary:Forty seven reinforced concrete walls with various opening configurations are tested in both one-way and two-way action. The test panels, with a slenderness ratio of 30, 35 or 40, were subjected to a uniformly distributed axial load at an eccentricity of one sixth of the wall thickness (tw/6). Apart from highlighting the experimental set-up; typical crack patterns, failure modes, and load-deflection behaviour of test panels are also reported. Actual test failure loads are compared to ultimate load predictions using the Australian standard wall design equation and also a recently derived formula specifically for walls with openings. The code equation is found to be inadequate for the many cases investigated whereas the derived formula was verified as being adequate in predicting failure load of walls with openings.
