NYC code was 20 psf wind for all buildings up to 100 ft tall. Just a nice flat wind pressure. No wasted time going thru the code just to come up 18.7 psf or something like that. The code guys must get paid by the page because half of ASCE7 feels like wind chapters now.
For people who use ram structural system know the struggle of installing an update and then your previously working model now has 25 slab edge warnings.
Enercalc has had some issues in the past but I love that program. Chris is always quick to respond and address potential bugs.
I've just...
I just use what steel beam size works in this scenario since most of the time in new construction we'll have a 2x top plate and can use the top flange hangers. It's different in a retrofit type situation of course.
If you're worried about it being loaded only on one side just run a quick...
Cut sheetrock up a few feet and install ledgers all around. Usually they are single story ranches so they are light anyway.
Definitely rare in NJ to lift without being in a flood zone (or environmental problem). Do you usually raise houses a full story up or put them back down low?
All the above depending on loading and sizes. Sometimes we weld the hangers on top. Sometimes directly attaching to top plate like in the Simpson book. Face mount hangers work as well. LVL packing is used all the time around here. The difference in cost seems like splitting hairs IMO. If the...
99% of lift jobs are because of flood zones and that also correlates with high wind area so uplift connections are always a focus around here.
There are a number of different Simpson straps and hurricane ties that we use depending on situation.
Some houses are slab on grades to start so you...
We do a ton of these types of foundations and not once did we ever have to worry about means and methods as XR said.
Typically if it's a block foundation they'll add at least one new sill plate and then we'll detail some type of uplift connector to the framing depending on the setup.
Lot less than you would think. Good lifting contractors pick up and move a house and you would never even know. It's when you are jacking up only an end wall or center bearing point to level a floor you notice a lot more internal issues.

That tech bulletin doesn't like this detail because of shrinkage concerns. And of course this is exactly what we had started to sketch up.
They do like the 2nd detail, which I'm assuming shows plates top and bottom instead of on the sides. That feels impossible to actually build on an...
We were just using the NDS and checking our work in WoodWorks, but we will look into that chapter for sure. Thanks!
That is a great reference, thank you. And I'll be sure to use the word 'slop' every time I can now when talking about bolts.
Yes. The video SW shared is a good example of how they are installed.
Those are shear plates. Split rings are just hollow rings.
And that is exactly our question. Does the shear plate give us meaningful help for this moment connection. Or are we better off spending money on a longer plate w/...
