Abstract
In order to evaluate compressive strength of centrally-loaded steel column at elevated temperature, new FE analysis techniques and assumptions of model were applied in this study. It also includes comparison with the existing studies, and a new design equation for centrally-loaded steel column at elevated temperature was proposed. The proposed equation was the most accurate of the three design equations(EC3, AISC, proposed equation) when comparing with the coefficient of determination on the simulated results and test results.
