Attaching to an existing Masonry Wall
Attaching to an existing Masonry Wall
(OP)
I have a new floor system that I wish to attach to an existing masonry wall. Is it possible to install a bond beam, or grout horizontally into an existing wall, to create a new bond beam for the attachment?
My thought was to attach a ledge angle, but based on the loads, I need to attach to a solid wall. This new floor is at a different elevation than the floor on the other side of the wall, so I know I wont be at a bond beam. Also, the existing wall is reinforced vert at 48" oc, but my loads require the attachment to be at 24"
Any ideas?

Grouting the cores solid is possible but it might be costly and difficult to verify.

A C10 or C12 would allow you to get two rows of anchors in at 4'-0" o.c. instead of 1 row of anchors at 2'-0" o.c. Should give nearly the same anchor capacity.
Would need to field verify which existing cells are grouted prior to fabricating the holes.
Just an idea.

You are not allowed to increase the stress in any existing structural element by more than 5% w/o bringing it into compliance with current code. I'd be willing to bet you've exceeded that 5% just in Dead + Live. If you have any seismic involved....ouch!
You can't by chance make it self supported can you?
