I've had some steel beams specd for a first floor cavity wall. The span is 3.42 m.
Under the section titled 'Bearings' it reads:
Bearings 203 x 102 x 23 UB stiff bearing length, b1 = t + 1.6r + 2T = 36.2 mm; O/A b 1 taken as 138 mm taken as 138 mm.....
If so, I assume I would add 138mm to either side of the span?
Does that mean a bearing of 138mm?
