centre post removal help
I have a 23'x23' attached garage, with living space above. It has a centre post in the middle of the garage holding up a 4 ply 2x10 beam, I would like to eliminate the post. How do I go about this? the living space above is one open room, there's no supporting walls above the beam. the beam just runs through the centre of the open room above.

Have you considered replacing the 8X10 with a piece of steel?
Is this "beam" a girder (underneath) or flush w/ the floor joists?
It is still supporting 264.5 sq' of floor...
X whatever your local code calls for.

I'm just a carpenter, not a structural engineer, and I would strongly suggest you consult one.
Consider that there's a valid reason they bothered to set that column there in the first place.
But looking at my tables and depending on what your code calls for, I think you'll lose too much headroom going with a "wood" beam.
It's calling for either a 5 1/4"x20" LVL or a 7"x18" Parallam.
Regardless, I think this would be further limited by how much deflection (bounce) would be acceptable in the floor above.
If you were to cut the joists back and hanger them into the sides of the PSL you would still pretty much have the same head room.
Steel might be a better answer.

never thought of cutting the joist back and hanging them from the beam, I guess thats why your a carpenter and I'm not. the place I got my truss from for the garage I just built, has a enginner type guy there that could probabaly tell me how big a beam I need for that span. thanks for your input!
