Subject: Is this pole barn braced enough?

North Central Alabama

I have a 40x60 pole barn that is around 16' tall on the eve's.I live in AL so I don't have to worry about snow load.But we have a lot of wind.The west side wall and gable on south side are closed in.I store hay rolls in the bldg. I had rather not have anything hanging down on the insides for me to tear down when stacking rolls 3 high.I could deal with braces if it meant a stronger bldg.
I read a lot on here about knee braces.Why are pic's sometimes turned sideways when you post them?

You can rotate the pics before you finish posting.I rotated them cw for you. I can't imagine that shed lasting long here with the winds we get sometimes, especially if it would be open to the west.

+1, local ranch built an 18' tall three sided hay barn. IIRC it's had to roof ripped off at least 4 times, probably more like a half dozen. They even went an put a piece of drill stem at the eve and tied it to the ground tryin' to keep that roof on. May have helped,,,,,,,, but still got blown off again.

AS posted, you need more bracing from post to truss and lateral bracing on end's to truss . . . . It wouldn't lost long here either. Nice looking shed though.

Edit: Are those simple floor truss's ? With no support at the mid-roof ? It's hard to tell, but there is a huge amount of force exerted toward the top of the poles if that is the case. It would appear (from pic's) that you need a truss type to equalize some of the outward force or the roof will push the middle down and soon you'll have a flat roof or collapsed roof ? Again, from the pic's ? It looks very "odd"

Look closely, note the truss rods tying rafters together. Agree it seems lacking in diagonal bracing though.

That building system is standard here. I can see several from my house that have been up for years. Those trusses are cheap and easy to put up. Crews routinely put up a 40x60 top only in a day. Again no snow load.

It would go a long way if you had another endwall. Those act as shear walls and with only one, the other side will want to fold like a house of cards.

Up here, they won't build a building half that high without knee braces, and x braces, between the poles. And the end rafters would be tied diagonally . lots of bracing needed. I do like the rafter look though.

I'm no expert for sure. We put up a 60x100 building similar to yours. Open on the East and South. It also has wood trusses and not metal but your building looks very similar to ours and ours has been fine for about 10 years now. I'd venture that 90% of the buildings here look very similar. Did you build this yourself or did someone put this up for you? How may buildings have they put up over the years?

Did Summertown Metal build that building.
They are building many of them here in my area
and seem to be holding up well. Most people here are using
8x8 post for more strength.

On some buildings knee braces would be part of a buildings planed engineered design. Where I have seen the braces (as in my shed up north here), the wood trusses basically sit on top of the posts, and the knee brace tie the truss in again and also support it from a couple feet lower on the post. Effectively stiffening the joint with another attaching point and reducing the real clear span of the truss. Your buildings metal trusses appear to be mounted to the top AND a foot or so lower on the post. So we are not talking apples to apples on designs here, and it makes it really hard to compare 2 completely different designs. And I think some posters missed seeing the cross brace under the center of your truss to help tie the center together and keep the peak in place .

I am not an engineer, and my opinion is worth what you paid for it.

That open corner at a minimum I'd enclose. And once framed sheet it with plywood to increase the strength of that wall section as a sheer wall. I also don't see X bracing under the roof trusses - the first 2 should be X braced from each corner, along with X bracing for each existing corner wall to the second column.

Talk to your builder. I think the trusses are engineered to a specific code.

We have been using builders using that kind of truss for about 10 years. Have two hay barns built from scratch and have had the same folks replacing manufactured wood truss type barns that have been damaged by tornadoes and one fire. The structures are built cheaply and fast. I think our barns are 14' to the bottom of the truss and we had the posts upgraded to 8" and walled in 3 sides including X bracing alernate bays. The weakest part is the end wall. You will want to be very careful not to let your stack lean on the wall. Have replaced every end wall (3) so far. Went back and split the spacing adding more posts than original and carefully stairstep the bales back from the end wall. The sidewalls with some 2x6 strapping on the inside stand reasonable bale pressure just fine.

Unfortunately the wrong straight line wind or tornado will take any of them down or at least take the roof off. Same for every building including metal frame structures.

Pictures taken with Apple hardware have some kind of indicator in the binary data to show the orientation. PCs don't recognize that but Apples do so when you look at the pictures in your Apple it turns them automatically. GIMP the software I use for working on pictures does recognize the Apple orientation indicator and as soon as I load an Apple picture it asks if it should rotate the picture. But I don't use that to look at pictures.

Question the builder, ask for their for prints with PE's stamp. Voice you concerns and keep records, including your insurance company. If there are issues down the road they are on the hook, IF they are still in business.

I agree with others that it needs attention. Would never have been built that way here.

I don't think I would worry about it. Lots of liter sheds around here just like that or less walls closed

X braces can also function as some of the strapping applied to the inside of the posts to prevent a bale from pushing the wall off the outside of the posts.

We set the first two layers of bales on end and try to set the 3rd layer on the round side, one on each stack of two bales. Invariably one of the top bales will end up sagging and pushing out on the wall so that is where we run the top 2x6 along the inside of the posts. If you do not have this strapping I would step the bales back from the wall a half bale as you add each layer. It is a pain to remove the metal siding and reattach the strapping.
