The corresponding design ultimate bending moments of the CFDST with regard to the design codes AISC and EC4 were also computed. The results revealed that EC4 and AISC can accurately predict the ultimate moment capacities of the CFDST with shear connector. | Evaluation of ultimate bending moment of circular concrete–filled double skin steel tubes using finite element analysis
