I want to remove a wall in a finished part of my house that used to be a garage. I went into the attic to see if the wall is load bearing and I discovered that the joists above the wall in question are already attached to a beam that runs end to end to two other walls. In other words I believe the wall I want to remove is not load bearing due to the fact that this beam exists and appears to be part of the original construction. The joists are 2x6 and the beam is 2x8s doubled up the joists are not hung by joist hangers just simply nailed into the beam.
The house was built in 1961 and I believe this was the common method used to attach joists. I am unsure of the species or grade of lumber used for the joists or beam and I understand this affects span distance. The beam isn’t quite centered in the house and it doesn’t run full length of the house. Looking directly at the beam the joists hung to the right span 11’6” from exterior wall to beam with no wall supporting them. The joists to the left span 13’1” from exterior wall to the beam, with the wall in question located directly under joists about 4’ to the left of the beam.
I know I can attach a beam to replace wall but my question is, is this needed since there is already a beam in the attic? Hopefully this makes sense I have pictures of everything and can provide other measurements and information if needed. I have not been into the crawl space to see if there are supports under the wall I want to remove. Also I noticed that were the joists meet the beam there is some seperation at the top of the joists from the beam, however they seem to be flush at the bottom of the joist. I understand this could be from settling or?
It’s worth mentioning this house was moved from its original loacation about 40 min away to a new location in one piece and set on a new foundation in 2005. I would like some advice and possibly a discussion about my plans for this project and ways to reinforce the joists themselves as there are no joist hangers or collar ties.
Thanks for anything you can contribute.
