A total of ten 6061-T6 aluminum alloy extruded H-section beams were tested under shear load. The primary design variables were the web slenderness, the shear aspect ratios and the end post conditions. A shear dominant failure mode was observed in specimens with the aspect ratio of 1.0 and a bending failure mode was observed in specimens with larger aspect ratios. Finite element models were developed and verified by the test results. Then a parametric study was carried out to generate an extensive numerical data pool on aluminum alloy H-section beams loaded in shear. The obtained test and numerical results with other available data were subsequently compared with the predictions according to Eurocode 9 and the Direct Strength Method (DSM) in AISI S100 and AS/NZS 4600. In general, the EC 9 provides more accurate results than the DSM formulae, but unsafe ultimate shear load predictions could also be obtained in cases of plastic shear buckling of the web and the relatively flexible flanges subjected to a fairly large moment. The DSM could provide considerably conservative predictions, because the rigidity of end posts and the effect of the stiffness of flanges on the interaction of bending and shear are not considered explicitly.
