Cold-rolled aluminium channel sections are widely used as primary load bearing members such as roof purlins, floor joists and rafters due to its remarkably corrosion resistance and high strength-to-weight ratios. However, when aluminium channels are subjected to shear forces, they may become susceptible to shear buckling due to the high web slenderness and low elastic modulus. This paper presents the details of experimental and numerical studies using the finite element method. The actual dual actuator shear tests program was performed on cold-rolled aluminium channel sections conducted by the authors at the University of Sydney to investigate the shear strength and behaviour of cold-rolled aluminium sections in shear. In this test program, a standard channel section supplied by BlueScope Permalite featured a depth of 200 mm, flange width of 76 mm and thickness of 2.5 mm was selected to observe the shear post-buckling behaviour. The aspect ratio was selected by 1.0 and 2.0 to maximise the shear action. A series of finite element models were developed using ABAQUS software to simulate the actual test. A good agreement is achieved by comparing the ultimate shear strength of cold-rolled aluminium sections in shear between the actual tests and finite element models. The ultimate failure modes of the aluminium channel sections from the finite element models are compared to those from the actual tests. Both the tests and finite element models show a clear shear failure mode with a diagonal shear band across the shear span with no effect of bending moment.
