BigH appreciate your perspective. I’m on the east coast, where soils can vary from unfractured rock to peat very quickly. I don’t believe this is one of those sites.
I also held the thought that giving the ultimate didn’t make sense for the reasons you gave. I suppose the general consensus...
Yes I’m familiar with the transition from allowable stress to limit states, and surely this wouldn’t be ULS or SLS. It’s either ultimate or allowable and I expected such language to be used on the drawing instead of design.
No they’re definitely not nominal footings, up to 13’ by 13’ so...
Working on a Canadian retrofit project now with foundation drawings from the late 80s. Foundation drawings call out “DESIGN BEARING PRESSURE 6000PSF”
Like many retrofits, we’ll be adding substantial load.
Maybe it’s my age but “design” means nothing to me. Is this intended to be ultimate or...
JoshPlumSE it's not an issue with the transition but rather an issue for one rafter in isolation. Consider the deflected shape of the rafter under lateral load as a simple beam: what's a reasonable limit on that deflection given that there's not really any lateral load present? Default would be...
First time poster, hoping this meets the forum criteria with respect to duplicate threads.
I just wanted to re-open the discussion on a closed thread in light of a recent client request:

I believe the structure in question was a storage tank...
The difference between UG-34 and App Y is that in UG-3, the flanges are separated by a gasket (metal or flexible) on the inside of the bolt pattern such that prying action is eliminated and no extra load will develop in the bolts or the flanges than what would be apparent from seating and...
