Load Carrying Capacity of Square and Circular Composite Columns under Axial Loading

Abstract

Load carrying capacity of composite columns under axial loading is the main goal of this research. For that purpose, some tests on steel columns of square and circular section filled with normal and lightweight concrete were tested to investigate the load capacity of such columns under axial loadings. Comparisons between Normal and lightweight concrete filled steel columns for different columns cross sections using Euro Code 4 were carried out. The test results appeared that both types of concrete filled columns failed due to overall buckling, while hollow steel columns failed due to local buckling. The circular columns show greater load carrying capacity than other sections regarding to its confinement for the same modulus of elasticity. According to the said results, the further interest should be taken onto the replacement of the normal concrete by any type of lightweight concrete due to its low specific gravity.
