a)
The characteristic bending moments are based on the assumption that lateral bracing to compression flange (at a spacing not
exceeding ten times the flange width) is in place.
Notes:
• Values shown are for non-loadsharing conditions. Where the
joist centres are < 610 mm a load-sharing factor K 3 of 1,10
should be applied to the permissible moment, shear and
bearing values in accordance with BS 5268.
imposed load is no greater than 1,5kN / m 2 . This is applicable
to the permissible moment, shear and bearing values.
• Data shown is taken from characteristic values, page 10.
• A K dom factor of 1.12 can be adopted when designing
residential floors within self contained dwellings where the
