Steel Angle Column Base Plate Design
Steel Angle Column Base Plate Design
(OP)
Hello everyone,
Could someone provide me with a reference that explains a way for designing base plates with Steel Angles (L shapes) as columns? AISC Design Guide 1 specifies the design process only for W-Shape and HSS/Pipe.
Thank you,
Anthony

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I am having trouble finding the section where lightly loaded base plates are discussed. Is that section available in the AISC Design Guide 1 (2nd Edition), if so where within the text?

If you don't have the software, there are other things to try.....but I thought I'd suggest that first.

It was used on a small work platform 36" above ground. I don't know the whereabouts of the supporting calcs.

For tension measure from the bolt to a reasonable point on the angle (will depend on the orientation) and make an assessment based on a conservative width in bending.
For low load applications where the arrangements are awkward to do the math on, just make conservative assumptions that keep the math simple. You're not going to save money on the steel compared to the amount of work you put in.
Realistically, the angle is likely going to force a hinge in the plate at the diagonal between the two tips of the angle. You also can't fail a plate without the hinge going to the edge at some point. So bending width equal to the plate width is likely conservative for a reasonably size, reasonable thickness plate.
