ABSTRACT:
A structural beam has a generally T-shaped cross-sectional profile with a column portion and a capital portion. The capital portion has a top surface and downwardly and inwardly converging sidewalls, while the column portion has downwardly and inwardly converging sidewalls and a bottom surface, with the rate of convergence of the capital portion being greater than the rate of convergence of the column portion. Such beam can be employed as a floor beam in a flooring system for a building structure, wherein the ends of a plurality of such floor beams are supported by the inner flanges on opposed foundation beams having an inverted T-shaped profile. The foundation beams can be positioned end-to-end to form shuttering for an in situ cast concrete slab. A layer of a thermal insulating material can be positioned on top of the floor beams, and a concrete slab can be cast on top of the insulating layer such that the top of the concrete slab is no higher than the top of the foundation beams.
