Generic Composite Steel Beam Details
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

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
• 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
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
