A composite beam is disclosed. The beam includes an internal horizontal beam ( 5 ), a composite slab that is positioned on and supported by the beam, and a plurality of shear connectors ( 15 ), embedded in the cast concrete and welded to the beam and connecting the composite slab to the beam. The beam is characterised by a reinforcing component ( 19 ) that is positioned so that reinforcing elements ( 61, 63 ) of the reinforcing component intersect a conical-type failure surface around the shear connectors in at least two different, preferably perpendicular, directions.
