BS 5950-4:1994 gives recommendations for the design of composite slabs with profiled steel sheeting. It covers slabs spanning only in the direction of span of the profiled steel sheets.
This code applies to the design of composite slabs in buildings. It does not apply to highway or railway bridges, for which reference should be made to BS 5400-5.
For the design of composite steel beams with a composite slab as the concrete flange, reference should be made to BS 5950-3.1. Diaphragm action produced by the capacity of the composite slab (or of the profiled steel sheets at the construction stage) to resist distortion in its own plane is not within the scope of this Part of BS 5950.
For the design of profiled steel sheeting as a stressed skin diaphragm, reference should be made to BS 5950-9.
