AbstractExperimental and theoretical studies have been carried out to predict the fire resistance of hollow steel sections filled with various concretes. This report deals with circular steel columns filled with bar-reinforced concrete. Using a computer program, the influence of the various study variables on the fire resistance of these columns, namely, column section size, steel wall thickness, load, effective length of the column, percentage steel reinforcement, concrete cover thickness to reinforcing steel, concrete strength and type of aggregate, were investigated. The results are described and the influence of the various study variables is discussed.
