Minimum Edge Distances as identified in BS 5950-1 2000 "Structural use of steelwork in building. Code of practice for design. Rolled and welded sections".

Notes;
BS EN 1993-3 2005 supersedes this standard and the edge distances in this standard seem to be a bit less than the ones I have listed. However I have maintained my figures in line with the original version.

It must be stated that connections under tension with the end edge distance (b = 1,4 D) cannot withstand the full load that is possible with the bolted connection. An end distance of B = 2D is required to achieve this maximum strength.
