<br/><br/> The main objective of this research is to study the effectiveness of employing lightweight concrete or fiber reinforced concrete or reinforced concrete in composite steel angled columns. The parameters of the study are: Compressive strength, Ultimate strains, Earlier concrete crushing, Non-linear Ductility, Local buckling of steel section and Mode of failure. Experimental investigation was carried out for twelve specimens (120*120*700 mm) of composite columns filled with plain concrete, Light weight aggregate concrete, Fiber reinforced concrete, and Reinforced concrete. Strength development, Compressive strength, Density of concrete and Modulus of elasticity for different mixes of types of concrete were investigated in order to be used in Finite Element Modelling as a parameter of concrete material. Using ABAQUS finite element program, models for composite columns of different types of concrete had been conducted. The Finite Element model was verified by the experimental results, and then used to investigate the compressive strength, load-deflection of overall column, and stress-strain curve for concrete type that filled column
