A Comparative Analysis of Concrete-Filled Steel Tube and Aluminum Tube Columns Subjective to Axial Load

Columns are the vertical members of the structure. A comparative study of two different types of confinement material for the concrete column has been carried out. This research adopted steel and aluminum tubes to confine the concrete column. Numerical analysis of confined columns has been done by a three-dimensional finite element model. A total of six confined concrete columns have been analyzed. The effect of increasing the area of hollow tubes increases the axial deformation capacity of concrete-filled tube column, load has been analyzed on the FEA model. A total number of six confined concrete columns has been analyzed. The analysis results have shown that the increment of the area of steel tube and aluminum tube decrees the axial deformation failure of the concrete column. FEA analysis results show that with the help of the concrete damage plasticity model different types of parameters like deformation, von Mises stress, logarithmic strain, and damage in tension can be plotted.
