N2 - Elliptical concrete filled tube (CFT) was modelled using finite element method to predict the structural characteristics such as strength, stiffness and ductility. The effects of tube thickness and concrete strengths were examined by using three nominal thicknesses (4mm, 5 mm and 6 mm) and three concrete grades (C30, C60 and C100) as concrete infill, nonlinearities of materials were taken into account in the analysis. The results of columns strength and load-axial shortening curves are discussed. The paper concludes that the factors such as thicknesses and concrete strength do have an influence on columns strength and the simulated models were validated using laboratory experimental results.
