Temperature Distributions of Protected Cellular Composite Beams Heated Three Sides

Article Preview

Abstract:

The fire design of structural members depends on its temperature distributions. This paper investigates the temperature distributions of protected cellular composite beams heated three sides. Modeling in ABAQUS indicates that the fire protection and the concrete slab make a big difference to the temperature distributions of steel beams. Temperature gradient exists across the web region of the steel beam. Comparison with predictions from European design codes shows a good correlation between each other, but some discrepancies exist for the top flange.
