Cheers Jon! Any chance we can get this thread unlocked? https://www.eng-tips.com/threads/lateral-system-for-row-houses.518536/page-2#posts And if we are doing wish list items, once the FAQs are all restored, if we can get some special consideration regarding deleting these two that would be...

Looks like a large number of the FAQs I created are gone with the new site/forum backend. I won't be rebuilding them. Cheers. I'll probably drop off activity here, if not cease, too. Considering. It's been fun, though. I was really intending that to be something of use to more than just me...

Ok, since I kind of have a hot tub project, too, I'll bite. 86.6 x 86.6 footprint = 52.2 ft2 (rounded down very slightly). and 650 lbs weight = 12.5 psf. add 100 psf live load (occupants) = 100 psf (5,200+ pounds, that sounds like a LOT of people, not 6-8, anyway). and 400 gallons (presuming...

Those moment frames are too close together to be plausible, plus effectively with no lateral system at the top of the house, there's a cantilever diaphragm on both ends of this house, the one at the top is way too long. I think I've already said this but it bears repeating. Rowing - I gave you...

StrEng007 - gte447f answered that question about bracing the stud. Your 'quote' of the OP (of yourself) doesn't seem to be what you actually wrote, however. It's a paraphrase. From the top: 1. How important is it that my studs align with the trusses? I'm used to 16" o.c. studs, but the 24"...

I feel like I missed this thread or missed this before. If the calculations calculate out, it's possible. If there's no calculation, you're skipping part of the load path. There's a few articles on that, but I'm not convinced anybody here is actually struggling with that. I've seen that kind...

I'd imagine for the typical structure the "you can drive a truck through the building" style of design doesn't hold. This is like a shotgun building (enfilade is a prettier term) but even those styles had walls in the left-right direction.

Cam I think the contractor just decided to put a joint there.

Only if you want it to resist code required loads in accordance with generally accepted principles of mechanics.....

Yeah that looks really outside anything that's been tested or used to base the provisions on.

If nobody minds I'll slap that into an FAQ for the AISC forum. [link https://www.eng-tips.com/faqs.cfm?fid=2919]1986 - Tension Only Bracing (effective Length Factor for the Design of X-bracing Systems)[/url] If you're looking to cite the article, here's the official version of that, from...

Yeah I don't know the provision but now that more neurons are working, if I recall correctly it's 4/3 of the reinforcing that is required by analysis is the alternate minimum, so it might be justifiable that way. Unless that's only for development length..... On a related note, this is a really...

Footnote a - you can't mix them with a plywood diaphragm in calculations for design. (I suspect the intent here is on the "same" level, i.e. plywood roof diaphragm and ceiling diaphragm. I'm going to quibble with you calling full height or continuous studs "balloon framing" in a gable. That's...

No. Stop being ridiculous and get a real analogy that isn't some fifth dentist silliness. It's not even a closed reference test. Go get some accuracy and come back later. Sheesh.

This needs a drawing. What you are describing currently makes zero sense to me. Normal forces in a slab don't develop from the weight of the slab, it goes into bending and shear. Or is this post tensioned? I'm also having a great deal of difficulty visualizing how a prestressed structure has a...

I wouldn't call it a design standard but Midwest Plan Service had some plywood gusset connected wood trusses circa 1960 that's never been updated. Those sort of don't rely on bending in the gusset, however, as they are "truss" connections. I'm not finding it exactly but this might be an...

Lofty - Inline photos are highly preferred for the future - use the camera icon and you can attach a jpeg directly. For your use, which appears to be indoor, the three plies can share load equally, provided there's a valid way for the load to get into all three equally (some of the LVL...

You probably want to locate the hot tub limits dimensionality on the design, and if it's close to the edge there's a higher Guardrail, likely... I would not blanket design for 50 psf, place the load where the hot tub is. Or design for "excessive" 100 psf load the whole area. As a usage note...

Either it needs to have shear transfer as needed to engage the other side of the concrete, or it needs to work ignoring the stuff past the cold joint. At least it's not in the width of the beam. And what do you kean we don't have calculations for this beam? That's not right action.

Answer depends on a sketch of the condition.
