Shear Nailing Like a PRO in Just 4 Easy Steps

[@dynajen1989]

I have always wondered, if we were really trying to make a rock solid frame, why we don't use adhesive on the wall and roof panels as well, just like floor panels or in some areas drywall. You would think it would help spread that shear load to far more surface area than nails alone.

[@AwesomeFramers]

@@dynajen1989 it does add strength BUT it makes the wall too stiff. So they decided not to require it in the code. I can't remember where I read that recently.

[@major__kong]

Bonding works really well with metal-to-metal with good surface preparation. On wood, there are different gotchas. The adhesive is often stronger than the wood fibers, and the top layer of fibers will typically pull off with the adhesive in a failure. Nails transfer the load deeper into the wood. There are a couple of other factors to consider. First, it takes 24 hours for a polyurethane adhesive to cure. You don't want the wall flexing, as it would during installation, until this cure is complete. So you may have to build the wall and not raise it for a day. Second, if a repair has to be made to the sheeting at some point after construction, e.g. storm damage, good luck separating the sheets from the studs without damaging the studs. See my comment above about the top layer of fibers separating with the adhesive, and ask me how I know :-) Not saying a bonded joint on wood is bad in this case. Just some things to think about.

[@willbass2869]

Thanks both to "major_kong" & "awesome framer" I had the same question....' why not glue that sheathing to the studs

[@kevinfarrell329]

​​@@AwesomeFramers not only not require it, it's forbidden for a standard plywood shear wall. As you said, it makes things too stiff. There's something called the "response factor" in the base shear calculation that essentially takes the ductility of the bracing system into account. Unglued plywood shear walls are well ductile, they get a "r-factor" of 7. A wide-flange beam stood upright in a block of concrete usually has an r-factor of 1.25. These numbers go in the denominator of the base shear calculation. So, bigger r factors mean smaller base shear numbers. The end result of the base shear calculation is a fraction or decimal, which gets multiplied by the weight of the building. Typically .25-.4 depending. So if you have a very stiff bracong system you have to design for more lbs/ft of lateral force for the very same building than if you have a more ductile system.

[@AwesomeFramers]

@@kevinfarrell329 do you have a reference? I recently read the same thing but can't remember where.

[@michaely4165]

One of the many things I enjoy about your videos is your explanation of the science and background behind the materials you use and how they are properly applied.

[@zamom]

His videos are terrific I wish here were my teacher in high school I’d be 10 years further into my career with his knowledge.

[@ToIsleOfView]

I love this detail about light construction. Wind damage is more common than seismic damage. This extra nailing could also help protect against wind damage.

[@MatthewHunting-ui9oj]

Love the Perkins Builder Brothers reference lol

[@disqusrubbish5467]

Worked for a short time for a guy who was a friend of the owners and didn't seem to care about keeping parallelograms at bay. In the end no one died, and the house didn't collapse but still... And yes, thank you for nailing it all together flat on the deck after squaring. Then tipping up...

[@buttermonkeyFTW]

5:49 I have been focusing a lot more on making sure the tools are dialed in on depth when we’re installing the plywood. A lot of the guys I work with don’t know any better or don’t care which frustrates me but I’m still too new in the company and profession to do anything about it besides what I physically do myself

[@lewishodge4935]

The worst example of inadequate shear walls I've seen was in a large track home subdivision in AZ circa 2008. One vertical sheet of 1/2" OSB was placed on each side of an outside corner; then another sheet was not required before the next 25 ft. Between OSB sheets were foam panels for stucco over foam, thinner foam over shear panels,. Couple this with the use of finger jointed studs and I had the expectation that structural problems would arise short of ten years down the road. I left AZ shortly after, so I don't know what the result/followup was. In my wildest dreams, I never thought they would use this type of construction on single story garage portals, BUT THEY DID and for TWO story homes as well!?

[@buttermonkeyFTW]

It’s wild that any engineer looked at that and thought, yea. This is a good idea.

[@lrc87290]

We had nearly the same on our two story condos in South Jersey Coast which is a high wind area. Plywood on the corners. Fire rated plywood 4ft either side of the party wall. Foam everywhere else. Some led in metal T braces. When we replaced the vinyl siding we replaced all the foam and corner plywood with Zip sheathing

[@lewishodge4935]

@@lrc87290 Good move!

[@major__kong]

When I remodeled my 1963 ranch on a slab in 2010, I did it mostly myself. I went down to bare studs everywhere. On the outside of the studs but behind the brick was some sort of fiber board. In the corners were 1x6's with pathetic nailing. No wondering I could hear my house creek and groan a little wind. I beefed the 1x6's up with construction screws, added retrofit bolts to the footers and hurricane ties to the trusses, and then did what you mentioned. But I did 8ft sheets of OSB on either side of each corner and in the middle on long walls, furred out the other studs (I only had access to the inside of the house), and did some structural connections between intersecting walls. It just wasn't worth it to add sheeting everywhere, especially on the inside where it was going to cause other problems like electrical box and door casing depth, and all I was looking for was the house to last long enough for me to get out of it. My main concern wasn't wind - nothing will stand up to a tornado - rather another earthquake out of the New Madrid fault in Missouri. I did a little research and another quake in that area would propagate fairly well up to where I live in Ohio. It's a lot better than built, but I'm not sure how much better.

[@MrHavokman]

If it were engineered it was probably adequate? Why do you say inadequate?

[@merlinsmith2431]

Glad I don’t have to install windows with nail flanges in this build, it would be so frustrating trying to find a spot for nails or screws between sheeting nails lol!

[@npsit1]

Good info.

[@raystraining3206]

Most shear schedules are 3/6 here in Fl for our 140 wind code. I've seen 3/3 in HVHZ 160

[@h2s-i9o]

3/6 should require 3x Material for framing or just use steel/icfs

[@chasebrown5532]

I’m curious if more money is spent on the fasteners or the wood materials for a framing package?

[@NickOvchinnikov]

wood fasteners are maybe 5 percent of the cost of the frame

[@nelus7276]

​@@NickOvchinnikovCan confirm. We prefabricate sheathed and insulated frames and where the total cost of the product is on average 150 units of cost per unit of area (not from the USA so most readers wouldn't understand the units anyway), all ironwares come down to maybe 5 units of cost per unit of area. Wood will be around 50.

[@johnwilliams3659]

@27:30 even after that test, I dont see a crack in that drywall

[@kevinfarrell329]

Camera was near top floor, bottom floors probably flexed more.

[@andyelliott292]

Would there be an advantage to glueing the shear wall for strutual rigidity with the nailing as discribed or wold that be conterproductive?

[@ronaldnielson8591]

Yes, that's my question, too. I built a garage about 45 years ago and glued the roof sheeting and all the siding (T-111).

[@NickOvchinnikov]

maybe a little, but nails work really well. we use 2 ½ x .131 ring shanks....

[@CDArena]

From the rack test video, I'd say gluing any two sides (minimum) would increase the rigidity. Is it needed in a low earthquake zone? Probably not. Gluing would greatly increase construction costs as well. Maybe limit this to the end panels on each wall? Depending on window & door placement, diagonal cut-in cross bracing might be more cost effective.

[@BWIL2515]

All that but also around all header joints if you cover the entire opening with one sheet and gluing I would think there is nothing else you could do to minimize movement. I like the idea and all corners something to ponder 😊

[@kevinfarrell329]

No, it is a structural disadvantage. You want the nails to flex back and forth. Crush into the plywood a little with each cycle, etc. That's how the energy gets released, as heat in the metal nails and mechanical destruction of wood fibers. A stiffer bracing system has to be significantly more robust from roof to foundation than a ductile one.

[@MrRafa2196]

Do you have product number for nails you use for sheathing? Cant seem to find 2.5” ring shank in a .131 with decent size nail head for the max nailer having to go back to 21 degree gun to do sheathing.

[@kevinfarrell329]

Why ring shank?

[@AwesomeFramers]

I don't use ring shank for shear walls, no benefit. Nail Gun Depot is where I buy nails.

[@gpgoggin]

@@AwesomeFramers I may be wrong here, but the nails that you show in the video appear to be ring shank and (hot dipped) galvanized. I've spoken to Nail Gun Depot and the only product they have in that length and shank diameter is electro-galvanized. Is that what you are showing in the video? Do you find that electro galvanized nails are adequate when they will ultimately be protected by Zip tape? I really appreciate your videos, they've been very helpful to me - so thanks!

[@AwesomeFramers]

@@gpgoggin Yep, I absolutely think they'll be fine where we build. If we were close to salt water, I'd check local codes, but these aren't exterior applications since the get covered by siding.

[@jamesoncross7494]

So do you have to do this with regular plywood? How about 3/4" T&G plywood on the walls?

[@AwesomeFramers]

If your wall sheathing is structural, then yes you have to shear nail it and block the panel edges if you are building to the current code. I would never spend the money on 3/4 T&G on walls, unless there was a specific need.

Please check the pinned comment for explanations on that 👍

[@buttermonkeyFTW]

I wish more often at my work we were allowed to sheet walls before we stand them. Makes life so much easier but unfortunately a lot of the time we can’t get our lull in a position to do the lift so sketchy extension ladder sheeting it is

[@disqusrubbish5467]

On the deck is the only sensible way. We lifted them up without machines but that was before "back problems"... Haha.

[@buttermonkeyFTW]

@@disqusrubbish5467Lol yea it would be a lot nicer but we’re doing 8000 sqft homes with only 3-4 guys so lifting some of those long walls isn’t feasible

[@kevinfarrell329]

I framed a 4000 sq ft house with 1.5 other guys, we built all the walls on the deck in stacks from biggest to smallest and had a crane come out. Stood all the walls in one day.

[@dakotamcdivitt1808]

That's the way to do it. Also, if the walls aren't massive, use wall jacks.

Dont build walls longer then 16’ foot you should be able to stand it up

And everyone that is a lick knows it’s about developing repeatable processes- so i’m curious if you can think of some other laws or lessons that let you succeed like you do?

I've never thought about it before.

[@kevinfarrell329]

A 4th way is with a moment column.

[@kevinfarrell329]

Check out Engineer Thor Mattesons's Skinny Brace some time. He takes a cantilever column /moment column which would normally have an response modification factor of 1.25, but uses a ductile connection at the top to get an r factor of 7. It's cool.

[@drelppod]

Given all this, how is zip-r ever able to pass these tests?

[@AwesomeFramers]

@@drelppod it does but requires a tighter nail pattern. I'm talking R3&6 panels

[@shenlonggohan]

Too much wood, thermal bridging, but how much added structural resiliency? Any at all?

[@AwesomeFramers]

Thermal bridging is a non issue for this house due to the climate it sees. We don't get cold and we don't get hot.

[@rolandherzfeld8231]

wouldn’t it be nice to have an attachment so you need not bend over while using the nail gun?

[@kevinfarrell329]

Fun fact, I believe the original guns were so heavy they had a boot attachment and a long handle and were shuffled along that way.

[@TH-cb9bh]

Why not just use glue like subfloor? Seems like that would be stronger than even using all those nails

[@AwesomeFramers]

Covered in a comment above 👍

[@steveharkins279]

This is kinda desptive in math in the rack test by Simpson, if one started with a 2 foot rip in zip then laid it sideways at the plate. Then by the time you get to second floor “one” spreads the stress with a full sheet across 1’st & 2nd floors. This way, one is daring any lateral/ rack stress to bend full 4 x 8 sheets of zip, a mathematical improbability to a factor of 5. Don’t believe me, Put it on the shaker table.

[@AwesomeFramers]

There is nothing deceptive about the test. It shows real world use of materials, e.g. sheathing that spans plate to plate.

[@steven7650]

lol i fired the guys on my last job site. Just could not get why this mattered and the language barrier didn't help.

I always use plywood, OSB is an inferior product, especially when moisture is around.

[@AwesomeFramers]

OSB is NOT an inferior product, and this have been covered many times in reputable trade magazines for going on 4 decades. Ply here will delimanate aftter it gets wet the first time, OSB doesn't here.

Zip sheets should never end at “plates” they should “seem” in the middle of studs… Zip sheets do “rack”, bare studs do “Liner” (or vertical load).

That doesn't jive with the SDPWS

[@steveharkins279]

@@AwesomeFramers ok that’s a significant read , but I’ll mussels through it. Still not sold on the foam layer between zip and wood stud. That is a weak point for the nail. Can we find any house built like this “failed “ from seismic ? That we can study? Does Simpson have film of this design on the shaker table? Not sold it quite yet. Wind is easy, seismic is the gorilla in the wall.

To me it would lower costs/ add strength to frame in regular zip. Let electric/ plumbing/ HVAC do their thing,, then foam the entire house.one monolithic wood cube glued together the entire bay to sheet. Rather than sheet with foam “nailed to stud” on the face.
