Started garage wobbles

You need to have braces during construction; these are often left behind since they are not in the way. They are on the wall.

 

[Nissens]

There is a recessed carrying beam of 170mm on the outside of the wall plate. It was the builder who recommended this precisely because the roof trusses didn't land exactly on the wall studs.

Yes, that's what I'm saying. It's probably only 45mm thick?
The wall studs are placed where you put them. If you want them under the roof trusses, you set them there... it doesn't matter if there's something odd at the gables...

Put it on the inside of the frame. Diagonally across a few sections. A regular board

You can also put braces in the sections of the frame with the same dimension as the studs in the frame. The important thing is that there should be two braces per section that go up to half the Height with a horizontal stud in between. Normally you use the sections closest to the corner on both sides of the corner. This way, you avoid problems with the boards on the inside.

there is an interesting difference between building in Finland and Sweden, in Finland wind protection gypsum is almost always placed on the outside of the frame, this makes the build completely rigid and weatherproof at an early stage, however, almost exclusively felt is placed on the roof and no råspont. I, who am a bit team Finland in this matter, think it's a strange way to spend money on råspont which in fact doesn't contribute much to the construction, but encase the frame in thin sheets where stability is needed. of course, the best is to have both, but if one is to be economical, I would skip the råspont and spend the money on exterior gypsum.

Yes, I mean standing studs.

Are you going to answer what you mean by "also"?
That is, what else besides the beam is supporting the trusses. I see nothing other than the beam that supports them..

Including a picture that shows how the standing studs are usually placed under the trusses.

Also referred to:
embedded beam or wall studs under the trusses.

 

[FredrikR]

Yes, that's what I'm saying. It's only 45mm thick, right?
The wall studs are placed where you set them. If you want them under the rafters, you place them there… it doesn't matter if it becomes odd near the gables…

Yes, but 170mm high and recessed in the studs.

Hello, nice build!
Before you do anything else, you MUST do the following.

What you need to do is brace the roof and walls. Take some scrap planks and first check that the house hasn't warped. Then, place planks at approximately 30-45` from the floor sill to the top of the wall, and check all corners to ensure the house is level (straight). You can adjust with tension straps to pull (tighten) the house so everything is straight. In the roof on (the underside of the truss), you can easily start by checking the center-to-center measurements of the trusses in the middle of the house. Temporarily screw a board right under the ridge all the way across. Then, as others have suggested, use hold-down straps in a cross pattern underneath the trusses from all four corners of the room.

Every year you hear of a new build like yours blowing over/collapsing. So take this seriously and take care of yourself and your loved ones; a garage can always be repaired, but not people. //Builder Bob

Hi, nice build!
Before you do anything else, you MUST do the following.

What you have to do is cross brace the roof and walls. Take some scrap boards and first check that the house hasn't skewed. Then place boards at about 30-45` from the floor sill to the top of the wall, check all corners to make sure the house is plumb (straight). You can adjust with ratchet straps, pulling (tightening) the house so everything is straight. On the roof (underside of the truss), you can easily start by checking the center-to-center measurements on the trusses in the middle of the house where you temporarily screw a board right under the ridge all the way. Then, as others have said, take hold-down straps and cross them under the trusses from all four corners of the room.

Thanks for the detailed response. Hold-down straps on the trusses hadn't even crossed my mind, great idea!

I also thought about climbing up and placing diagonal braces between the trusses to make them a bit more stable 🙂

The problem is the same, the risk of the trusses collapsing when the wind blows from the "wrong" direction, especially with a heavy snow load.

In this case, it was found that there was no other stabilization than the metal plates, and after several decades, the screw holes in the plates had worn out due to excessive movement in the trusses, and everything gave way and fell.

What is your point, by the way? Is it okay to build garages with loose trusses without any other stabilization than the tongue and groove? Even my garage from 1940 or something, measuring 5.5*3 meters, has braces between the trusses.

My point is that it's likely not going to collapse as some suggest.........Not that I follow news reports religiously, but we are probably very fortunate in this country when it comes to buildings collapsing....In the case you mention, it sounds more like a radical design/miscalculation error than it solely being due to what you mention.

 

[Daniel 109]

It does happen that frames collapse before any sheet material or facade has been added.

I don't know if it's completely missing here, but it's definitely insufficient.

The wall plate is not intended to take loads from above, they are meant to prevent the wall from bulging outward/inward.

What is supposed to take the loads from the roof trusses then?

 

[Daniel 109]

The studs in the wall.

 

[Nissens]

What then is supposed to take the loads from the trusses?

The studs in the wall. A top plate only takes horizontal forces, not vertical...

 

[Nissens]

Yes, but 170mm high and recessed into the studs.

And what else supports the roof trusses? I'm still curious about what you meant.
And it's still the case that one usually has vertical studs under the roof trusses.

recessed beams or wall studs under the rafters.

Yes, but "also" means there is something more. What is the other thing?
