Shear buckling design of webs in aluminum beams

The local buckling of aluminum members subjected to bending was analyzed using finite element analysis of the beam web stability under shear. The finite element analysis was verified by experimental data obtained from the literatures. The calculations analyzed various factors influencing the shear buckling of aluminum plates such as the width-to-thickness ratio, stiffener spacing, alloy temper, and end post. Calculational methods were developed to predict the buckling strength and the post-buckling strength of aluminum plates subjected to shear. The results show that the method is sufficiently accurate for analyses of stability of aluminum plates subjected to shear.
