I am in the process of moving a beam into the attic to be flush with the ceiling joists that run perpendicular. My question – What kind of load is on the ceiling joists? Do I need to worry about the ceiling joints moving either apart or together when I cut them to slide the beam in? Is the roof truss load on the ceiling joists?
I have a house 25’ x 60’ with a hip roof. The area of this project and work is central to the house where the ceiling joists run parallel to the common rafters.
To further explain. My living room was 17’ x 19’ with an inset of 8’ for a patio area covered under the existing roof line. I have put the exterior wall out to the roof line to include the 8’ into the living room. The ceiling joists run the full 25’ out from one exterior wall to the old roof line that covered the patio area (and is now the new exterior wall). The ceiling joists over lap on top the old exterior wall (8’ back from the new exterior wall).
I am face placing two 16” x 20’ glulams flush with the bottom of the ceiling joists. The beam is reaching from one interior wall to another and each of these walls are on top of poured concrete basement walls. I will hang the ceiling joists off both sides of the beam. Before I take out the old wall, I will have both sides of the old wall fully framed with temporary walls to support the ceiling joists from downward movement. Should I be concerned with any other direction of movement when I cut the slot for the beam in the ceiling joists?
