good morning

I am a looking to remove a load bearing wall carrying the attic space floor joist ,
it is essentially a crawl space attic, just hvac and duct work
the joist are 2x6 splice over the 2x4 load wall and then another continuous run has a header in the attic a 2x12 resting on the corner post and perimeter wall carrying 2x8 toe nailed

My question is i want to replace all with a 3x12 LVL by Louisianna pacific
run it from the perimeter walls to a load beaing post carried through to the cellar.
Can i use teco hanger and nail into the side of this LVL and where would i find the load bearing capacity.

Your millwork guy should know the engineering specs. for all that.
You need an engineer to look at this. Don't mess with structure and assume it will be fine. If it fails you are liable for everything. Don't mess around with this.
I have always gone to my supplier and explained what I wanted to do. They will run the engineering specs on the LVL's and tell you the load points and even the hangers and how to connect the LVL's together.
Knowing the specs of the beam is only half of the equation.
The other half is knowing the CALCULATED LOAD of what the beam is holding up (ceiling load + any roof loads bearing upon it).
The presence of ducts etc has little to do with anything, as they would already be considered within the standard floor load calculations...unless there is an extreme weight condition...ie: bath tub, heavy equipment.. Check with an architect, engineer or draftsman for actual calculations as there are no shortcuts on this one.
"That's plenty big" is not a calculation!
Hire an engineer or an architect, before you do anything with load bearing partitions.
exactly hire and engineer and make sure your butt is covered :thumbup:

I think you need a professional engineer dont try it your self or you will be messed up.
Moving/changing a load bearing anything requires a permit and inspection here.
