Even when doing work in the same geographic location, I've found that there are very few "typical" details. I have some typicals, but I almost always tweak them for each job.
Great discussions, by the way.
I just wanted to suggest that perhaps not having E&O insurance wasn't as big a deal 30-40 years ago. MY firm is 1 year old, and I can't imagine that I'd be able to make it 40 years without needing my insurance in today's society. I appreciate your perspective...
Thanks Splitrings.
I'm not a member of ASABE, so I don't have access to that.
Thanks for your input. One question - Do you get the bearing to check out for the rebar embedded? I haven't plugged through my calculations yet, so I'm not sure what kind of uplift I'll have, but it will probably be...
Splitrings, do you know if the UC4C is much more expensive than the UC4B (0.80 vs. 0.60)? I'm reading that there should be a minimum of 0.60 for typical pole-shed posts - so I'd like to specify the 0.80 especially because I will probably be burying it in concrete, but I don't want to give the...
Thanks Mike and Mike! The building is open on 3 sides (one of the three butts up to an existing building, so only two sides are truly "open"), so I only have cladding on one side to help out with transferring the wind loads. I do have a concern with the totally open end that butts up to the...
I have been asked to design the foundation for a pole shed. They said they typically dig an 18" diameter hole, drop the 6X6 wood post in, and pour it solid with concrete half way up.
I have a couple of concerns.
1) is it okay to bury treated wood in concrete?
2) will the concrete bond to...
I'm analyzing an existing structure that has what appears to be cold-formed steel joists. They are 8" deep, with a 2" flange width, and a return lip, similar to standard SSMA joists/studs. The odd thing is that the punchouts are spaced 6" o.c. The punchouts are "football" shaped - 4.5" wide...
Thanks a lot everybody. I will go ahead and have them saw-cut the top of the plank. I like your idea hokie about fastening outside the flange. I think I'll have a wide continuous plate over the top flange, that way I can increase my bearing area for the plank as well.
Not that this matters, but are they still using the '97 UBC somewhere?
It's tough to answer all your questions, since there are no "quick" answers. But, one underlying factor to what you're asking about is the strength of the base under the slab-on-grade. The strength and durability of a...
That's a thought, Mike. I'm not sure if it's feasible to add 2-3" topping, as it is an existing roof, and they would have to rip up the entire roof insulation, etc. to do that. I'm also concerned with the ramifications of adding that much extra dead load. But, if that's what's required to do...
I'm used to seeing the steel in the bottom only, but I'm sure it could be either way, depending on the situation.
For my case, let's assume a worst case. Is it worst case to assume only steel in the bottom? If so, is it necessary to saw cut the plank over the new beam?
Are there other...
That was my thought, TAE.
I don't know if this complicates matters, but there's about a 4' cantilever on the far end. I've attached a sketch of my situation.
Thanks for your input, everyone!
Another question I have is what is the best way to fasten the top flange to the precast for lateral...
I have an existing precast plank roof, and we're adding a taller addition, so it will cause snow drift on the existing plank. If I install a new beam line to break up the existing span into two smaller spans, do I need to saw-cut the precast over the beam so I don't produce any negative moment...
I agree with the people who say design for full snow. I do not know of a reference to confirm that's required. But, I don't think it would take much to get enough ice and/or snow pack as a "base" on the grating, and the snow would accumulate on top of it.
I would not combine it with other...
Delagina - thanks so much for the spreadsheet! Unfortunately it doesn't address my unique situation, but that is an EXCELLENT resource to have for the future.
Slickdeals - thank you for your calc! that was above and beyond the call of duty. That does make it as simple as I was hoping it...
