Larger opening on load bearing wall
 
1 Attachment(s)
I hope you guys can help me out.

I have attached a document (html) that shows my house dimensions and load walls

On the third diagram, the yellow highlighted area shows were I want to open the existing 32" opening to 96". Currently the header over the 32" doorway is (2) 2"x6".

I have done some investigation and calculations and of the opinon that (2) 1 3/4"x 11 7/8" LVL beams should more than support this span. I am asking for some opinons on that.

Also, below the first floor, under the load bearng wall in question, there are three 1 1/2"x 9" joists within an 18" span so I again belive I have the strength there to supprt the load each end of the 96" header.

I look forward to your responses.

Thanks...Greg

Greg: IMHO I don't see an issue. In truth I even wonder if the wall in question is even load bearing. Normally with a construction like you have with a center steel I beam, normally the loads are from center to outside walls. If that wall is running parallel to the joists, which in your print it appears to be, it is not "bearing".
