Mechanical Behaviors of Slender Steel Tubular Columns Filled with Steel-Reinforced High-Strength Concrete

Abstract:

To study on the mechanical behaviors of the new slender steel-concrete composite columns that are named after steel tubular columns filled with steel-reinforced high-strength concrete(STSRHC), the mechanical models of slender STSRHC are established for the analysis with the finite element software ABAQUS. There are seven influencing factors on the mechanical behaviors of slender STSRHC, they are: slender ratio, eccentricity, the thickness of steel tube, the yield stress of steel tube, the yield stress of inserted steel, the cube strength of high-strength concrete, the shape of inserted steel cross section. The results show the results calculated by software have good agreements with the tested ones; slender ratio, eccentricity and the thickness are the most effective factors on the mechanical properties of slender STSRHC.
