| Abstract | ||||
| This paper addresses a numerical simulation of composite columns, in particular Concrete Filled Steel Tubes 'CFST' subjected to biaxial bending. Comparison with some experimental models is conducted in order to understand better the behavior of CFST and to validate the computation methodologies and results obtained. Results for various load eccentricity and different columns cross-sectional area are obtained, analyzed and discussed. In addition, the analysis considers material non-linearity of concrete and steel. The experimental results are also compared with the failure loads predicted in accordance with Euro-Code 4 (EC4). The results verify the applicability of the non-linear finite-element method as an economical and expedient alternative to expensive experimental work. | ||||
