Steel with a Minimum yield strength 280 N/mm.
Beams are assumed to be simply supported.
Load and deflection are calculated using a safety factor of 1.6 and an allowable stress of 175 N/mm.
Results given are for Pre-galvanized steel
Beam loads are calculated from the column face and effective length in BS5950.
The tables show:
1. The max safe working load,
2. the load to give 1-200 deflection,
3. load to give 1-360 deflection – the deflection
used will depend on the installation designer.
This also applies to Point and UDL loads
