Temperature Distributions of Protected Cellular Beams Heated Three Sides

Abstract:

The fire design of structural members depends greatly on temperature distributions. This paper focuses on the temperature distributions of protected cellular beams subject to fire. Modeling in ABAQUS indicates that the fire protection makes a big difference to the temperature distributions of cellular beams. A continuous drop in temperature in the upper region of the web occurs due to heat transfer from the web to the top flange, and consequently to the ambient. Heat transfer between the web and the bottom flange also takes place resulting in non-uniform temperature distributions in the lower region of the web. Comparison with predictions from the European codes shows a good correlation between each other, but with some discrepancies.
