Fatigue and the Ability of Composite Precast and In Situ Concrete Slabs to Distribute Concentrated Loads

The fatigue strength of composite in situ and precast concrete slabs has been studied following the failure of a suspended floorslab at a West Midlands factory. Nine short (600 mm long) lengths cut from standard precast units (400 mm wide) have been placed side by side and used to cast 17 ‘transverse’ specimens 600 mm wide tested on a simple span of 3.18 m (i.e. normal to the main span direction of the standard floors).
