The calculation formulas of CFST members under single stress state are derived, and the relative limited equations of CFST members under multi-stresses state are given also. The calculation formulas of rigidity and deformation of CFST members are derived. Finally, the effects of creep and sMnkage of concrete, the change of temperature for environment and the welding on the member are briefly introduced.
