HSS wall plastification
HSS wall plastification
(OP)
Proposition: welding 1/2" dia. threaded studs to exterior side (centered on wide face) of 6"x2"x1/4" rectangular HSS for some connections.
Question: Are the traditional HSS T-section wall plastification equations of section K2 appropriate to use here?
Something tells me that one or both of these checks may be unconservative for such a relatively small diameter branch "member" (1/2" dia stud)
From Eq. K2-3 phiPn = 4.70 kips
From Eq. K2-4 phiPn = 10.3 kips

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.

RE: HSS wall plastification
Quite right. For plate bending checks, I would go with yield line analysis or Roark's as you mentioned.

Initially, I figured I could cover the plate flexural yielding by using the "chord plastification" limit state checked by the first equation.
Is there a strict difference between the terms "yielding" and "plastification"? It just seems like yielding for tube connections.
