Based on the results of axial compressive tests of lightweight aggregate concrete filled steel tube (LACFST) columns,the influence of slenderness ratio on failure mode and bearing capacity are studied.The bound slenderness ratio and stability factor calculation results of the empirical formula are compared with the test results.Analyses show that bound slenderness ratio as the demarcation of elastic-plastic damage and elastic damage mode can be calculated by Euler formula.The result of Euler formula is lower than that of the empirical formula.And the larger the slenderness ratio is,the lower the ultimate bearing capacity and stability factor are.
