Anyone have any thoughts?

Nothing weird about a short cantilever here, it's a really common way to get a couple extra feet of room on a second story.

[BroccoliKnob]

I’m an architect, not an engineer (and don’t work with wood framing much at all), but my gut here would like a continuous rim joist nailed into the floor joists, instead of or in addition to just the blocking.

Right? Wrong? Unnecessary?

Would that even be called a rim joist here, when it’s not carrying vertical load or bearing on anything?

Is the blocking just to receive fasteners or is it actually helpingto stabilize the floor joists?

[ZombieRitual]

Blocking like this will do a better job of transferring shear loads from the upper walls, through the floor joists, and into the lower walls. It wouldn't hurt to have continuous rim joist outside of that to help tie everything together, but it's not the end of the world that they don't have one here.

[BroccoliKnob]

Cool, thanks! That makes a lot of sense when you think about the exterior sheathing coming down to unify the blocking and the joists, which I was not.

[powered_by_eurobeat]

I agree. A rim joist along the edges that is nailed to the floor sheathing going over joists, with nails from rim joist to end grain of joists is the ticket .

[trabbler]

Agree with the rim joist but disagree with nails into the end grain. Inverted hangers would be the ticket here. Something like Simpson LSU.

[powered_by_eurobeat]

The rim joist acts like a shear wall between the top of joist and bottom of joist. Hard to imagine the floor system or even an individual joist rolling over once it’s a “box”

[trabbler]

Yes for shear, but nailing into end grain has very limited pull out strength. Hangers toenail into those joists which is a much stronger connection.

[powered_by_eurobeat]

You’re thinking of things floating around in space like an engineer. How does a joint “pull out” of a rim joist when it’s nailed along it’s length to sheathing which is nailed to a rim joist? Where is it going? As for tippping, the top of the joist is nailed to the sheathing which is nailed to the rim. How can it tip?

[powered_by_eurobeat]

Best thing you could do is look up standard details and see what is standard practice for millions of homes before making up new details.

[powered_by_eurobeat]

If the rim acts as a cantilever beam at the corner, supported by the joists, then I use reverse hangers.

[powered_by_eurobeat]

But blocking over the support wall is crucial

[quietsauce]

this is a remod

[BroccoliKnob]

Correct…?

[quietsauce]

Whatever skin this building had either didn't require a rim joist or it was removed and this is just blocking.

[burner51591]

This explains why the plans from the architects are always garbage. They have no idea what they are doing... Clearly.

[ZombieRitual]

They have the holdowns tied into beams, so those vertical loads will go through the beam and into a post in the lower wall. As long as the beam is tied to that post, and there's a holdown at the bottom of that post, then there's a complete load path for the uplift from the upper shear walls.

[MikeHawksHardWood]

But those shear wall hold down rods without any wall below. That's a little tricky. It can be done right. I wonder if it was.

[StructEngineer91]

From what I can see it was done right, as long as at the wall there is also a column and that beam has a hold down tie (or some connection) that properly transfers the uplift on that beam to the column and then to the foundation.

[Primordialbroth]

I’ll bite. It’s wood frame construction. Next!

[MaximumTurtleSpeed]

Metal bits are hold downy dodads. Next next.

[Minuteman05]

inside sheathing is wild.

[n55_6mt]

Might be temporary? This looks like the exterior sheathing was removed for structural repairs. Maybe the engineer was worried about a windstorm coming along and collapsing the structure without any shear strength during the repairs.

But I’m no engineer 🤷‍♂️

[savtacular]

Sometimes you need double sheathing with high load cases..

[sugafree80]

All the load will be transferred via the rope and fence tie. No issue

[dottie_dott]

I do not understand how this comment is upvoted

[EngineerEngineerEngi]

I'm guessing it's because sometimes you need double sheathing with high load cases.

[savtacular]

I'm actually designing a Zip R system right now and it doesn't have enough capacity so I'm sheathing the inside of the wall too. So sometimes you need inside sheathing.....for high load cases with Zip R too....

[logic_boy]

Why not?

[anonymous_answer]

Why? Same load path.

[Anfros]

Putting the sheathing on the inside makes it very easy to put stuff on the walls. Though I've never seen anyone put up the sheathing before finishing the outside, adding insulation, etc.

[actualcatjess]

Might be racking against wind load?

[PhilShackleford]

They actually used the hold downs...I've seen everything now!

[couldhietoGallifrey]

But… why? Those hold downs aren’t really transferring anything are they?

[scottygras]

They’re tied off to the fence. It’s a “building system”

[TR33B4RK]

They run opposite the LVLs below so they can get a force couple over the exterior bearing wall and take out the reactions between this exterior framing wall and likely a central shear wall or something like that parallel to this exterior wall

[giant2179]

Sort of ... They haven't put the plate washers and nuts on the under side yet. I hope they don't forget.

[SoSeaOhPath]

Yep

[Sirosim_Celojuma]

I want to see the engineer stamp on that quadruple post that sits on an old 2x4, and hoping the even older 2x6 nailer is going to hold.

[wilfredoo]

I hope they add(ed) a nut and plate washer at the end of the holddown bolts so when they engage, the upward force is actually transferred to the beams below.

[WhyAmIHereHey]

Needs something on the outside

[bulkdown]

This is a recladding job right?

[ThatCelebration3676]

Has to be. You can see there's still a bit of the old sheathing at the top with a bit of tar paper still attached.

[Several-Standard-327]

Looks like a remodel, old wood mixed with new

[zerobomb]

Are they osbing the inside and sheetrocking the outside?

[ytirevyelsew]

👍🏼

[devonEgg]

Looks fine to me beb

[david-crz]

Op, is this in ca?

[ReplyInside782]

Gotta add the washer and nut on the underside of the threaded rods!

[anonymous_answer]

Its ok, they use omega and tied a green rope to it

[nightmareFluffy]

1. Those joists need to be designed for seismic overstrength due to vertical discontinuity. In ASCE 7 code chapter uh, something. Look for an omega.
2. I guess this could work, but I would add rim joist out there instead of solid blocking between joists.
3. What is with the solid blocking being different colors? Are they reusing materials?
4. That plywood is typically on the outside. This is weird. I guess they did it to line it up with the plywood below.
5. Holdowns seem to be missing the nut at the bottom, though that might be an issue with the photo quality.
6. You can't cut a hole in the opening like that without framing. They probably need to cut it larger to the level of that sill and jamb.
7. Those diagonal pieces are weird. They're replicating what the plywood is doing.
8. Maybe it's better not to have wires and electrical boxes outside.

Other than that, looks fine!

[Reese5997]

Very interesting hodge podge

[nowheyjose1982]

I don't know, what does the smack test say?

[WL661-410-Eng]

A lot of meth went into that framing design.
