Gusset plate design for pin load 1

[umr10]

In the construction field, we use quite a few single pin connections for our temporary support structures. How should I design the gussets for this single pin load. I'm familiar with the Whitmore section but because I have a single pin transfering the load(compression) into the gusset I'm not sure how to develop the load in the gusset. We typically design with ASD. Normally I would look at the tribitary area produced by the Whitmore section (60 deg included angle) and get a compressive stress. Then I'd look at the gusset plate as a column with its lenght from the end of the connected part to the column for example. But with a single pin, I'm a bit lost.
Thanks

What is the diameter of the pin, you would need to check bearing on the plate, if the plate goes into tension you would have to check shear/tension rupture. If you want to treat the plate as a column (which seems reasonalbe) with the whitmore section, maybe use the average width of the whitmore section as the column and see how you stand, if its a tight design, go to a thicker plate.

That sounds resonable APETR26542 (the average whitmore area). That was what I was leaning towards.
This connection will typically be in compression.
I'm looking at a 2-1/2" pin diameter. Thanks.
