What spec governs built up box sections larger than 20x12x5/16
What spec governs built up box sections larger than 20x12x5/16
(OP)
AISC Rectangular HSS Sections go up to a max size of HSS 20x12x5/16. The design of sections up to that size clearly fall within the specification of AISC Steel Construction Manual.
What if you make a built up box section beam, for example, out of 1/2" plate to create a 24" x 18" x 1/2" plate box.
I am struggling to find a clear definition of sizes where AISC spec no longer applies, and what specification would apply in this case.
Any advice is appreciated.

If it is a structural member and not a bridge or other separately coded structure then AISC rules. Our duct was not carrying anything else so it was not an AISC item.
