I would like replace a 64" section of a load bearing wall with a beam and 2 support posts. The current wall is 2x4 pressure treated sill plate on top of poured concrete, 5 2x4 vertical supports and double 2x4 header.
I am looking for advice on materials to use. I am thinking about using 4x4 p/t supports, and doubled 2x8 for the beam. On one the left end of the new beam I would probably just nail the support beam the existing 2x4 on the other end I'm not really sure, but it will be perpendicular to a another wall that will be built (see proposed design below). Will this work?
If there are any major structural concerns, I could make the span shorter, but I would like to keep it as wide as possible. How should the beam be attached to the supports? Finally, any considerations for distributing the weight at the base? Thanks!
