Buckling behavior of 6082-T6 aluminum alloy columns with box-section and L-section under eccentric compression
View through CrossRef
Experimental studies of 29 pin-ended columns, including 13 box-type and 16 L-type, extruded from 6082-T6 aluminum alloy under eccentric compression, were performed in this paper. The buckling behavior, stability strength and deformation preformation of all the specimens were obtained. A numerical investigation of aluminum alloy columns under eccentric compression was conducted by using finite element analysis software ABAQUS, and the simulation results were verified with experimental results of 29 columns. The results showed that the FE model proposed by this paper can well predict the stability bearing capacity and the deformation characteristic for aluminum alloy columns under eccentric compression. Finally, based on the experimental data and a number of numerical calculation results, a revised interaction equation recommended by Chinese Code for Design of Aluminum Structures to predict the stability bearing capacity of 6082-T6 aluminum alloy specimens loaded by eccentric compression is proposed.
