Abstract
This paper presented a numerical investigation on the bearing capacity of domestic 6061-T6 aluminum alloy columns under axial compression at elevated temperatures. Firstly, based on the existing test data, finite element (FE) models of aluminum alloy columns with rectangular and circular hollow sections were developed. The FE models were accurately calibrated on the basis of the available experimental results. Secondly, a finite element analysis on the bearing capacity of domestic 6061-T6 aluminum alloy columns with thirty four cross-sections was conducted and 2108 numerical points were obtained. Subsequently, according to the finite element results, formulae to estimate the coefficient of stability of aluminum alloy columns at elevated temperatures were proposed. Finally, the proposed column curves were compared with test data and column curves of different codes. It is showed that the proposed column curves were well applicable to the aluminum alloy columns at elevated temperatures.
