Laterally Unsupported Plate Bending Resistance in Strong Direction
Laterally Unsupported Plate Bending Resistance in Strong Direction
(OP)
Hi,
In a situation like the sketch attached, how would we determine the thickness of the plate? It does not fall into a particular situation as listed in table 4-2 in S16.
Thanks in advance.

I would check shear and bending on the plate. For factored flexural compressive resistance, I would use Table 4-4 with effective length = 2L +b where be is the flange width of the supported beam.
If there are any horizontal loads parallel to the supported beam, the plate must be designed for bending and the column for torsion...messy detail.

The kicker on the WF is a good idea for the torsion to the beam.

Mn = Cb*(1.52-0.274*(L*d/t^2)*Fy/E)*My < Mp
or
Mn = Fcr*Sx = 1.9E*Cb/(L*d/t^2)*Sx
