Research on the Axial Bearing Capacity of Concrete-Filled Rectangular Steel Tube Short Column

Abstract:

Under the action of axial compression, it is difficult to deduce the capacity of concrete-filled rectangular steel tube (CFRST) short column in theory because of the complex constraining force between the steel tube and concrete. This paper uses two methods to study the axial bearing capacity of CFRST short column, the first method is to consider the main factors influencing the axial bearing capacity of CFRST column based on a great deal of experiments and use multiple linear regression method of mathematical statistics to obtain the formula of the axial bearing capacity of CFRST short column; the second method is to simulate the axial compression test of CFRST short column by using the powerful structure finite element analysis software ANSYS, and determine the axial bearing capacity of CFRST short column through 3D solid modeling, rational meshing and correct loading method. Those two methods provide new thoughts for forecasting the axial bearing capacity of CFRST short column.
