Abstract

In order to study the mechanical properties of steel tubular columns filled with steel-reinforced high-strength concrete (STSRHC) under eccentric compression , this paper establishes the formula of bearing capacity , analyzes the effect of eccentricity, slenderness ratio, strength of materials and other factors on the bending column’s mechanical properties by the finite element analysis software. Then, we will establish the bearing capacity formula through the regression analysis of data. The results reveal that the calculation results based on software agree well with the experimental data; eccentricity and slenderness ratio have large influence on the mechanical properties of eccentric compression members, strength of materials and shape of steel section have small impact on it; the calculation results based on the formula for the bearing capacity of eccentric compression agree well with the experimental results. The conclusions possess certain instructional significance for the design of new columns.
