Strengthening joists after removing support beam
I am needing to redo some stairs that are very steep and only have an 8" wide tread. The problem I am running into is when I calculate new stairs with a wider 12" tread I am running into a center support beam as I climb up or down them that runs the length of the house. This beam needs to be removed to give me the head room I need. The beam supports four 2x10 floor joists that butt together on top of it. My idea was to sister a 1/4" thick 9" wide by 12 foot long steel plate on one side of the joists attached with 1/2" hex bolts to basically allow the joists to then span the width of the house which is 28 feet unsupported. Would this work? Thanks!
