Sorry. What I meant to say was this: It doesn't sound like you understand how this all works. Please consult a structural engineer local to your area and have them design whatever it is you're trying to achieve. This is not a job for an iron worker, and I very much doubt anybody on this...

I mean this in all seriousness... please hire someone competent to do this for you.

BA, this is why I always specify the column pour stop to be 1" below underside of slab.

I just want to take a moment to thank everybody who contributed to this thread. There is a LOT of food for thought here and this will surely impact our approach to the wording in the report and the information we provide. If anything interesting comes of this, I'll be sure to update the...

BFstr, I'd rather not share any pictures as to limit chance of identification. The building is a slapped together old mining mill way out in the middle of nowhere. Minimal seismic, but decent snow loads.

LittleInch, rest assured I'm thankful for all of these responses.

I'm not as familiar with ACI as I am with CSA, but if the member is meant to act like a 'beam' (horizontally oriented flexural member spanning between supports) I believe it should be detailed as one.

I think external bracing is probably the way to go. One side is inaccessible so it'll have to be rigid, but a small price to pay, and one the demo contractor will be thankful to hear of in advance anyway.

I have no doubt that this is how it's working, but it was certainly not meant to by design. I can see the ends of the bracing that was cut. In one location they left half of it lying against the equipment they installed. In another, you can see from when the building was built a note written...

That's a good idea.

Thanks Dave, except I've been asked to certify the building as safe to enter from a structural perspective...

So I'm tasked with assessing if a crew of workers can enter a building safely. It's an old industrial PEMB type building (moment frames in one direction, bracing in the other, wind resisting gable ends) and in pretty bad shape, but has stood in place in its current state for probably 25 years...

EngDM, my comment was more to point out that the fee is small with respect to what it could mean for your designs, especially if you're dealing with a remote site. I do remote site designs all the time and have them on speed dial. I suspect there's more to it than the seismic calculator. I...

Just call Env Can. It's 200 bucks and you have something to hang your hat on. A little difference in elevation can make a huge difference in snow load, to name just one example.

You'd have to design the footing and CMU wall as a cantilevered retaining wall, and you're good to go.

It is a point load, yes, in an idealized scenario. However, as you sound like you realize, there are a few hoops to jump through to convince yourself that it's an idealized point load at the top of the beam. Firstly, the vertical load has to make it through to the beam, which the hanger...

Immensely helpful, thank you both.

Does anyone have a resource identifying the structural detailing of a standard 40' shipping container (or, 'seacan' if you're in the know)?

Try checking compression perpendicular to grain.

When significant movement is intolerable, I typically use friction and at-rest pressure (using Ko instead of Kp).
