Metal Building X bracing

[Boosted73Z]

Hello everyone, I’m in the process of having a 40x40x14 red iron metal building erected, their in the process of installing the sheeting now and the type of x bracing used is a flat band steel screwed to the outside of the columns under the sheet metal, i never saw this method on a metal building before, I’m no engineer but I figured it should have steel cables with turnbuckles for a building this size, suggestions?

Why dont you ask them ??? Seems like either way would work and the flat band is a lot neater. If the building is engineered that way I would think that it is fine.

I did ask them, they said they was going to recheck with the engineer and let me know, they never told me what the engineer said, just kept going with the erecting process and the band method is what their using, to me the bands seem loose with no way of adjusting like cables.

I don't know where you're at in the country but a 40x40 is probably fine with that. Smaller buildings can use the sheeting shear action to brace the building and be just fine. My building in TX is 36x48 and only has cable in the roof. None in the walls.

I’m in South Louisiana, that makes me feel a lot better about the flat bands, i guess i feel funny about them from working in larger metal buildings doing mechanic work all my life an seeing only cables.

Cable and turn buckles allows for adjustment, but if every thing is true and square you should be able to bolt bracing in with no adjustment needed.

We use either Rods, Cables or angles on the building we design and not every use that method, do you have sealed drawings by a Licensed Engineer? If you do, keep them in a safe place, you may need them in case some thing fails in the future...

I would get a hold of the engineer's drawings, but I have seen banding used before although cables is more common around here.

My 40X60X20 has rods in weird places so I'm sure it's all done based on engineering and loads and cost.

The one on the far end only has one brace, next to one of the garage doors yet the section the left of it doesn't have one. And then the roof only has is in the center section. I'm just glad that there are engineers to figure all this stuff out.

In my building 60 x 100 x 20 they used rods, but they were there to square and plumb the red iron before the siding and roof were put on.

I always thought they were just there to square up the structure and prevent 'racking' until the skin is put on. I don't see how any adjusting could be done after all the metal is screwed on.....it would all pucker and warp.

That’s exactly how the builder explained it to me, I thought the cables were there for additional support from wind, not just to square it up.
