Design of aluminium alloy channel sections under minor axis bending

In recent years, numerous research works have been reported on the flexural response of aluminium alloy tubular cross-sections. However, studies monosymmetric cross-sections and particularly channel (C-) sections are limited, albeit their increased usage in structural applications. This paper aims to address this knowledge gap providing an improved understanding about minor axis bending behaviour C-sections through experimental numerical investigation. total 14 specimens made from 6082-T6 heat-treated were subjected four-point bending. Tensile coupon tests also performed determine mechanical properties examined alloy. The obtained results analysed discussed. A series geometrically materially nonlinear analyses carried out study performance two alloys orientations over a range cross-sectional aspect ratios slendernesses. utilised assess European design standards. applicability Continuous Strength Method Direct is evaluated. An alternative method based plastic effective width concept proposed for slender accounts inelastic reserve capacity which accordance with observations.
