Compression weld thickness for angled beam

Tekla Connection Designer

Environment

British Standard

When the compression flange has a properly sawn end which is perpendicular, a bearing fit can be assumed between the flange and the end plate.

For beams, nominal 8 mm welds can be assumed to suffice, for lighter beams with a flange thickness of 12 mm or less then 6 mm welds can be assumed to be appropriate.

For haunches from section cuttings, the same nominal welds are required but with increased leg length to allow for the angle of the incoming haunch flange.

S > = 1.4 *s_nom/(min(cos((90 – qh)/2), 0.7) + min(cos((90 + qh)/2), 0.7))

Where
snom = the nominal weld sizes given for the beam case above i.e. 6 or 8 mm,
qh = the angle subtended by the haunch with the horizontal.
