I have a pole barn that is 32 ft wide. I need to free span 32ft. Im gonna take the pole out in the center so it will be a free span. There is a lean to that is attached to that span. I need something to support the lean to and span 32 ft. I was gonna use some 2x12 and stager them and make a header with putting a steel plate in the center of the header. Will this sag or will i need a 2 lvls with a steel plate?

or a scissor type truss... Do you need to clear span it for the full length. Can you post a cross section of what you are trying?

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Double wooden trusses at least 3ft between top and bottom chords.

 
That's a relatively long span....hire a local structural engineer.

 
Taking the pole out in the centre sounds like much more of a concern to me....

What's the purpose of the new beam? Any loads to be hung off it or coming into it from the roof?

"pole barns" are quite individual and removing or adding beams or poles could seriously impact the structural integrity.

Rally needs some drawings and photos to move this forward anywhere.

Also: If you get a response it's polite to respond to it.
 
You cannot get LVL's with a steel plate to span 32 ft. Take Ron's advice.
 
ok, I'm a dummy ...

are there any truss elements adding load onto this beam ? (or maybe feeding load to the pole)
ie is the beam acting as a true beam (with transverse loads), or is it an axial member (reacting thrust from the roof) ?

if there aren't then self-weight is the load causing bending,
if there are, then there is framework to support an upper chord ... to work in conjunction with the existing "beam" to make a more effective beam. (but then this'll be Ron's suggestion, of getting a structural engineer involved).

The man has a $90000 camper that he keeps under his pole barn and he wants to let the slides out but cant bc there is a pole in the way. The pole is on the the back wall of the pole barn. the barn is 32x50. The pole that I need to take out is on the back wall where the gable is. There is also a lean to attached on that back wall that has been added on. The man wants to take the pole out that is basically supporting the lean to in the middle. Im not worried about the pole barn. Im worried about the weight of the lean to once i take out the pole. I was gonna add poles beside the existing poles and concrete and anchor together so my header could just support the lean to and it sit on top of my poles. Ill try to get some pictures as I have not started this project yet.
 
"the pole is on the back wall" ? How will removing a pole that is on (or very near) the back wall help with opening the van sides(?) up ?

if the pole is on (or very near) the back wall, could you add a pole on the outside of the barn (to replace this internal pole) ? yes, you'd have to work around the lean to.

You will need new foundations/column in addition to the question you are asking about. If they have a $90k camper they can pay for $2 - $5k for an engineer to evaluate this so the camper is not turned into scrap if the repair should fail.
 
Ok. That answers my first question - clearly not a DIY job. New question - are you an engineer? If not, I'd advise you to hire one...
