I have to replace about 10 feet of a bearing center wall with a flush beam. The area above the space is the attic with the joists lapping over this wall. The area below is a finished basement. My questions center more around supporting the beam at either end. I plan on having one end terminate on top of the end of the remaining section of the bearing wall with the other end on top of a non bearing partition wall. The plan is to tripple the studs at the end of the remaining bearing wall and to tripple the studs of the non bearing wall below the beam. This will transfer the load to the first floor (basement ceiling). The basement is finished with a drywall ceiling. Is it better to cut the rock and place a lally column directly from a footing to the underside of the floor sheathing under the load or block between the joists and run the lally column to the bottom of the blocking. I’m not sure if an existing basement partition wall (non bearing) is going to fall directly below the new point load. If so, can I just fill in with blocking between the joists under the load and tripple the studs in the wall below the load? I figured this wouldn’t work since there is no footing under the wall which would mean demoing part of the wall to dig and pour a footing making it easier just tlo use a lally column which would be concealed in the wall after it is patched. Finally, if the point load created over the end of the existing bearing wall doesn’t line up with studding in the center bearing wall in the basement, should studs be added to the basement wall in addition to blocking between the joists or can the double top plate distrubute the load? Sorry, I am having trouble visualizing all this with the closed walls. Any advise or pointers is appreciated.
