Abstract :This work intends to numerically investigate the impacts of bonding carbon fibre reinforced polymer (CFRP) laminates to either the web or the flange of 6061-T6 aluminium alloy I-beam on the lateral torsional buckling (LTB) characteristic. The effect of laminate thickness, fibre orientation angle, laminate length, and laminate location was examined. In all hybrid I-beams, web and flange thicknesses were kept equal to those of aluminium (Reference) I-beam. Finite element (FE) models of aluminium and aluminium/CFRP hybrid I-beams were developed using Abaqus/Standard. Model verification was carried out by comparison of the numerical findings with experimental results available in the existing literature. A strong concordance was observed between the experimental and numerical findings, with a relative error of 3.3% at the critical LTB bending moment (Mcr). Attaching a 3 mm-thick CFRP laminate, aligned at 0° fibre orientation, to the flange of an I-beam increases the Mcr by 47.5% compared to the aluminium I-beam.Keywords : Yanal burulma burkulması, Sonlu elemanlar analizi, Hibrit I-kiriş, Alüminyum, Karbon elyaf takviyeli polimer
