Welding I-beams together

[SandburRanch]

I need one of those. Let us know if you go commercial and start working your way north.

FWIW: My barn is built with trusses that are done the same way and is a 40' span spaced 20' apart. Also 12" beams although I don't know the weight. - and no reinforcing plates. I'll see if I can get a picture tomorrow.

Not a very good picture, but it's the only beam visible and a lot of sky background washes out the detail. It looks like the web and the flanges are welded and that's pretty much it.

Finished up the purlins today.

I am going to close in the gables and maybe about 4 of the sides. The tin won稚 be in until Thursday.

The connection between columns and the beam does not have a good path for stress. Consider welding plate on end of beam

^^^^^^What he said!

I'd like to build a steel building, myself. Any way you could share the rough cost of materials? Either, expected price per foot or general difference in cost between steel and wood structures? I would like to build a 30x40 garage or something of the like.

I'm no engineer nor credentialed welder,just took note where weakest point was in things that failed. I find collar ties and tying columns togeather to prevent rafter spread add's more reinforcement than plates at joints. You likely plan doing that while filling gables in.

What you see pictured is $1,500 in materials. That is I-beams, concrete for the columns, and the purlins.

I expect the tin for the roof to be about the same cost. My guesstimate is around 3k total.

I was watching NOVA great cathedrals and thought of your building. All your stress will be where wall meets truss, a combination of downward and rotational. See arrow in pic

Royking, your picture shows what I was concerned with in my comments

For our Potato store with 12" Beams The peaks were all done with a flat plate welded on each beam and bolted together,
Same with the uprights bolted to a flat plate welded on top It was made in a factory and came as a kit ready to be erected
and bolted together. the engineer said it was rated to stand up to 50 ton weight on the roof. The uprights were 20' apart.
and a clear span of 60' wide

You have probably got some 12 beam left I cut a piece to fit where joist meets post see pic

That is a good idea. Unfortunately I don't. I bought four 30' beams and cut them 17' & 13'. 13' went in the ground and and 17' up top. After I trimmed them to size I had no piece over 6" long.

I did Add some more material to it though.




We got the tin on the ends today. Tomorrow if the weather cooperates we will do the roof.

Looks really nice bdog! Is that a Chihuahua getting prepared to christen your carport?

 

[RoyKing]

Closing gable in change the whole structure, very solid now

 

[Streetcar]

Looks good, the added material at gable changes beam into a truss

 

[bdog]

Thanks guys. Now I can sleep better knowing not everyone thinks it is going to collapse.

Yes that is our Chihuahua or our little sewer rat as we like to call her.

When I built my steel building, I laid short pieces of galvanized roofing between the beams, resting on the lower flanges,,
that material is, in my case, 6 inches below the actual roof,,

That gap creates an air gap, and the summer heat can not radiate down,, it stays cool in the building,,

My SIL has virtually the same building about 1/2 mile away,, but he does not have the extra layer of material,,
his shop is like an oven in the summer,,,

Since my drop in pieces were only 48" long, the local roofing company had hundreds of them, as they were drops from cutting roofing to length,,
I was able to buy the pieces for $0.50 each,, which was WAY more than the roofing company could get for the drops as scrap,,,

Great idea and even better execution! I like using air as insulation. Actually, pretty effective.
