The jacketed vessel I'm analyzing was built in 1959. None of the original design calcs, datasheets, or drawings match the as-built vessel. I'm to "update" the calculations on the jacket closure bar.
Turns out the bar itself is okay, but it imposes a large moment on the shell, causing failure. (This was assuming no repad--just closure bar-to-shell.) Later, I found out that there is actually a repad between the closure bar and shell...and gussets on top of the closure bar!
My question is, how to I take credit for the repad and gussets? Surely they add something to the strength of this attachment, though I don't personally know how to calculate this. I don't think a WRC 107 analysis is appropriate for this.
Any suggestions?
Thanks!
