Fire resistance of composite slabs with profiled steel sheet and of composite steel concrete beams. Part 2: Composite beams
Due to the large increase of use of composite beams in buildings, it was felt necessary to have a better understanding of their behaviours in case of fire. Composite beams, as for as this research is concerned, are made with a bare or insulated steel section connected to a concrete or a composite slab. This slab is attached to the upper flange of the beam by shears connectors. The research was shared in four main parts: experimental investigation of the fire behaviour of two types of shears connectors (studs and angles) in order to derive force-slipping relationships versus temperature; experimental investigation of the fire behaviour of composite beams, either simply supported or cantilever or continuous on three supports; validation of the capability of a numerical model to estimate the possible slipping between the steel section and the slab at elevated temperature; development of simple calculation methods for assessing the fire resistance of composite beams, taking into account the risk of failure of shear connectors and local buckling of steel sections on intermediary supports. Results of this research are foreseen to be incorporated in the next draft of Eurocode 4 part 1.2, dealing with fire design of composite structures.
