Removal of Load Bearing Wall
Removal of Load Bearing Wall
(OP)
We have a situation where arch. need to remove exist. load bearing masonry wall supporting roof structure. Roof is in step there with about 3 ft level difference at wall location. Joist and beams are resting over this bearing plates. We are proposing new columns but my question is how can i keep that 3 ft block masonry above the low roof or either we can suggest to remove that infill with stud.

If the new beam is to be wood, you may consider removing the masonry and using a lighter wood infill for the fascade.

Just for curiosity, is there any practically way to hold the wall and introducing the new beam to support it, i can't visualize how to insert new beam in load bearing cmu.

I've seen this done with steel channel sections bolted through the wall before the masonry below the channels is removed. The channels are sized to act as a beam supporting the load that was supported by the bearing wall.

How about drilling the holes in a deflected-shape pattern?
The construction sequence might be something like this:
1. Drill the hole at one end and install the channel with one bolt.
2. Lift the channel to an angle such that the center is at its calculated deflected position under dead load.
3. Drill and install the center bolt.
4. Jack the other end of the channel into position, drill, and bolt.
5. Drill and install remaining bolts with epoxy to fill gaps.

Does your proposal work for 30 ft span. We recemmend this technique for small span lintels but what about 30ft or 40ft span.
Thanks
RE: Removal of Load Bearing Wall
have used the channel system described above, but for something like 8-10' openings, not 30'-40'. For that span, you're talking a fair size beam, I would think.

This is sounding less and less practical, but I still think it's an interesting idea.
