Based on the method of construction safety analysis on hollow steel tube of concrete filled steel tubular(CFST) frame structures previously presented by reference[1],a finite element analysis(FEA) modeling was introduced and performed for hollow steel tubes in a 12-storey CFST frame structure under construction loads.The stress and deformation of the steel tubes were analyzed by using the FEA modelling.Finally,the influence of different construction schemes of the CFST frame structure was discussed primarily.
