Simplified model to predict load-bearing capacity of concrete-filled steel tubular laced column

A simplified method using an equivalent slenderness ratio was suggested to calculate load-bearing capacity of concrete-filled steel tubular laced column in this paper. The significant differences between compressive and tensile strengths of concrete-filled steel tube were considered. The comparisons between the predicted N-ue and the tested N-ue showed that the predicted method gives generally good predictions of the test results.
