Question Removing support posts in basement.

The new span will be 23' uniformly loaded with joists 16" on center. I would like to do a combination built up 2 x 10 wood beam with flitch plates to achieve a 1/360 of 23 stiffness. The dead load is 70 psf and the live load is 40 psf. How many plies of Dougles Fir and 1/4" x 9 1/2" steel plate would it take .

Welcome to the forums! Have you thought of using double or triple LVL 9 1/2" beam? Would save a lot of steel work.

Would a triple 9 1/2 LVL span 23'. My math might be off but I come up with 1760 plf. using a combined live and dead load of 110 psf. If so what would the deflection be?
