The Compressive Behavior of Horizontally Casted Concrete Filled Steel Tubular Members with Consideration of the Process of Concrete Casting
Concrete casting effect and the hooping effect of concrete filled tubular members is considered in the study of this paper. Firstly, standard stress-strain relationship of concrete and steel is chosen to simulate others’ test, and meanwhile the calculation results by nonlinear finite element analysis are compared with the results of the test. Then the bearing capacity of horizontally casted concrete filled steel tubular members under axial compression is contrasted among different construction processes. Finally, the effect of slenderness ratio of concrete filled tubular members is studied so as to reveal the relationship between the bearing capacity and slenderness ratio.
