Research on Stability of High Strength Aluminum Alloy Columns Loaded by Axial Compressive Load
This paper reports experimental study of 17 high strength aluminium alloy specimens of type of 6082-T6 under axially compressed load including I-section column, rectangular hollow section. The general-purpose non-linear finite element analysis software ABAQUS is adopted to simulate the mechanical performance and overall buckling of aluminium alloy columns. The feasibility of finite element method has been verified through the comparison between the simulation results and the test finding. Finally, based on the experimental data and numerical calculation results, a useful column curve formulation to calculate the coefficient of stability of 6082-T6 aluminium alloy columns loaded by axial compressive load is derived. Comparison between column curves from proposed formulation and different code and test results has been presented, from which the validation of the proposed formulation has been verified.
