| Abstract: | Through 4 CFDST hollow interlayer axial bearing capacity of concrete columns filled steel test research, preliminary discussion on CFDST square steel tube hollow interlayer compressive mechanical properties of concrete column and steel hollow interlayer load-carrying capacity and flexural stiffness of concrete to improve results. CFDST square hollow interlayer concrete filled steel tube column is analyzed destruction characteristics and the main form of damage. Research results show that in the scope of this test parameters, CFDST hollow interlayer concrete filled square steel tubes column can effectively improve the bearing capacity of axial compression column and column bending stiffness; Damage to the CFDST square hollow interlayer concrete filled steel tube column has a preliminary understanding. CFDST was determined and the calculation method of bearing capacity of concrete filled steel tubular axial compression column is verified and compared with experimental results. |
