Composite Steel Beam Design • 4No. Open cores for composite steel beam design • Generally 16mm Ø Transverse reinforcement • Generally 19mm Ø 125mm long shop welded shear studs • Reduced ends required where flange width is less than 191mm • Square cut units acceptable where flange width is greater than 191mm • Minimum flange width of steel beam 178 mm (*) (*) Based on slab length tolerance of +/- 5mm BISON HOLLOWCORE UNIT CORE BUNG 4No. T16 TRANSVERSE TIE REINFORCEMENT SHOP WELDED SHEAR STUD COMPOSITE STEEL BEAM

Composite Steel Beam Design • Minimum 150mm effective depth • Maximum 260mm effective depth • Shear studs provided at specified centres • Generally 1.0m width of compression area for internal beams • Transverse reinforcement for beam / unit interaction – 350mm max centres

Composite Steel Beam Design • Consider bearing of the units in the temporary case • Design Guidance Within SCI Publications 287 & 351 • Lateral instability of the steel beams during construction (*) (*) Specifically where MEWP’s are running on suspended slab

Composite Steel Beam Design Benefits • Shop applied shear studs – not affected by inclement weather • Significant tonnage savings when compared to non-composite solution • Additional tonnage saved with the introduction of Cellular beams • Top flange can be left un-painted without additional fire protection • Whole frame can be galvanised without effecting composite design • 2B Progressive collapse inherently dealt with using composite steel beam • Enhanced diaphragm action with the interaction of shear studs • Composite steel beam design can be achieved without structural topping
