Abstract:Carrying capacity of steel reinforced concrete columns with double circular steel tubes under axial loading was studied. Based on the stress-strain relationships of the core concrete, the external concrete and steel tube, steel materials, a steel reinforced concrete columns FEM analysis model was established. The calculating method and principle of the axial compression capacity were analysed, then the existing formula was improved for steel reinforced concrete columns. The validation of equations were carried by comparing with the results of the FEM analysis for actual project.
Keywords:steel reinforced concrete columns; circular steel tubes; axial compression capacity
