treated PSL in an exterior CMU pocket

[SLTA]

Hi folks,

I have a project where treated PSL beams need to be pocketed into CMU walls in an exterior application, and I can't find guidance on a detail. With steel, I'm used to requiring a grout-packed pocket with anchor bolts down into the CMU to hold the beam in place, but that doesn't make sense here. I'm also concerned about water ponding. Can I get some suggestions, or a recommended detail?

cheers.

1. After-set bolt a metal bucket to the wall...or

2. Mount the beam to an inset bearing plate with side plates in the wall, with rebar welded to the underside of the bearing plate embedded in the wall, and a 1/2" air gap between any cmu or grout.

Cheers, Mike, thanks! The bucket was my first hope, but the loads are too great. #2 it is.

Just to make sure I understand - the rebar would be set while the grout in the cores is still wet? Otherwise how would you get the grout in the cells below? Or is it an epoxy retrofit?
