Abstract
A composite floor or ceiling structure which comprises a profiled steel deck supported by a plurality of I-section steel beams each having an upstanding web bordered by upper and lower flange plates and covered in situ with concrete. The deck comprises a plurality of side-by-side elongate profiled deck members each including an upper generally horizontal surface bordered by downwardly and outwardly inclined side surfaces. The upper flange plate of each beam has formed in its upper surface a plurality of grooves in a pattern to increase bonding between the beam and its covering of concrete. Preferably, each supporting beam is rolled as a single piece with the width of its lower flange plate greater than that of its upper flange plate to define a supporting platform for the steel deck.
