Design of Composite Beams using Precast Concrete SlabsPre-cast concrete floors are widely used in building construction, but there is little detailed design guidance on their application in steel framed buildings. It is estimated that close to 50 of floors used in steel framed buildings in the UK use hollow core or solid plank slabs. Most of these applications are in regular steel construction in which the precast slabs sit on the top flange of the beams, but there is an increasing number of composite frames and slim floor constructions where the precast slabs are designed to interact structurally with the steel frame. Composite action can be developed by welded shear connectors attached to the steel beams and by transverse reinforcement, but this form of construction is currently outside the provisions of BS 5950-3: 1990 and little design guidance currently exists. Due to the fact that this type of construction is not properly covered by the Codes of Practice, this publication presents design guidance on the interaction and detailing of precast slabs (of hollow core or solid plank section) that are supported by composite beams or slim floor beams.
