Behaviour of Fire-Exposed Composite Steel/Concrete Slabs
The development of a mathematical model for analysis of the thermal and mechanical behavior of composite steel/concrete slabs during fire exposure, with the aim of improving European recommendations and increasing knowledge, is addressed. Focus is on composite slabs with additional reinforcement as a fire resistant measure. A thermal model based on finite difference theory which takes temperature dependent thermal properties of concrete and steel, the evaporation of moisture and arbitrary fire exposure conditions into account, is used to analyze the two dimensional, transient heat transfer in the fire exposed slabs. Heat balance equations are formulated by means of heat resistances and capacities and are solved using an explicit method (forward difference). A mechanical model is subdivided into two submodels for analyzing the cross sectional behavior and the structural behavior respectively.
