Existing there are 3 - 2x10 girders across the 26'wide foundation which are attached into the foundation walls at each end and supported across the basement by 3 lally columns approximately 6' apart.
I want to remove the one lally column that is the first column from the foundation. This would create a span of 12' from the foundation to the "center" column (see 4 photos attached).
I've hung 2 - 12' 91/2" LVLs sandwiching the existing 2x10s.
To support the ends of the LVLs, I've placed 5-king studs (2x4) on each end, supporting the "5" girders (2-LVLs and 3-2x10s), one next to the foundation wall and one next to the "center" lally so the span between the new king studs is 11' 4".
The kings studs are bolted through using 1/2" x 10" carraige bolts in the top and bottom 3rd of the studs.
The LVLs are bolted 16" O.C. staggered top/bottom through all 5 girders also using the 1/2" x 10" carraige bolts.
The extra images include the basic house size and a photo of the house. Facing the front of the house, we're working on the left front support.
I'd like to find out the maximum loads the original was verses the remodeled maximum load as a comparison so:
What is the maximum load of the original design of 3-2x10 spanning 6'?
What is the maximum load of the 2 new LVLs (with the 2x10s sandwiched) spanning 11' 4"?
Do the maximum load of the new LVLs meet or exceed the maximum load of the original design?
Can I now remove the lally column?
