Summary

Steel members have the advantages of high tensile strength and ductility, while concrete members have the advantages of high compressive strength and stiffness. Composite members combine steel and concrete, resulting in a member that has the beneficial qualities of both materials. This paper presents a numerical study on the behaviour of partially encased composite columns eccentrically loaded under compression till failure. Using numerical simulations, the load capacity of these composite columns were evaluated by means of nonlinear geometric analysis. Variation of the slenderness coefficient of the columns was carried out in order to analyse its influence on the behaviour of composite columns under compression and analyse the coherence with relevant codes. The finite element software used in the numerical analysis was TNO Diana, suitable for the field of civil engineering as a result of its vast library of materials. As a conclusion, it has been found that as expected the slenderness coefficient plays an important role in the behaviour of composite columns, changing the load capacity and the post peak behaviour. In addition, it is possible to obtain a load capacity forecast of partially encased composite column using codes of practice.
