Temperature analysis of steel -: Concrete composite slim floor structures exposed to fire

This paper presents a heat transfer model to calculate the temperature of composite slim floor beams exposed to tire. The interface thermal resistance between concrete and steel and the effect of fire protection can be accounted for in this model. Using this model, the fire resistance of the composite slim floor beams can be calculated and the effects of the significant parameters such as load ratio, section size of the beam, additional reinforcement and fire protection can be evaluated without the necessity of testing.
