Composite Steel Beam Behaviour with Precast Rib Flooring

Floors consisting of precast ribs supported on structural steel beams and in situ structural topping are a common form of composite floor construction.

Floors consisting of precast ribs supported on structural steel beams and in situ structural topping are a common form of composite floor construction. In this article guidance is given on the modifications required to previously published design guidance for computing shear stud capacities to adapt them for use with precast rib flooring systems. In addition consideration will be given to steel beam top flange stability during construction using this type of flooring system. COBENZ 97 is a popular spreadsheet based programme used for steel composite beam design. Explanation is given to allow designers to use this programme to design composite floor systems utilising precast ribbed floor systems
