Fire Resistance of Composite Beams Composed of Rolled Steel Profile Concreted Between Flanges

Abstract

Fire resistance tests were performed for composite beams composed of rolled steel profile concreted between flanges. In the present paper, the fire resistant test results and numerical analysis results are described. As a result of the fire resistant tests, the relation between the fire resistance time and applied bending moment of the composite beam is clarified. Analytical results agreed with tests results and consequently, the analytical model can be used to predict the behavior of this composite beam in a fire.
