    Below Grade CMU Wall Grouting Requirements

    I don't know if it is prescriptively required (sorry for not addressing the "meat" of your question), but depending on the membrane protection, it might not be a bad idea to fill the volume so that water can't collect and sit in there. This comes up more for residential where I think it's one of...

    CMU - Bond beam reinforcement minimums?

    BSVBD, thanks for the reply and for clarifying. Wouldn't want someone extrapolating the wrong idea. All I'm talking about is providing a solid area so that eccentric loading isn't dependent on a single face shell or web, as well as connecting a unit to adjacent units so that I'm not counting on...

    CMU - Bond beam reinforcement minimums?

    I've typically only known the "best practice" bond beams at the tops of walls to be mainly for the grout accompanying the steel, filling all voids, and providing a solid bearing for anything being built in or connected to the top of the wall, but the steel is still important to tie it all...

    lack of bearing of CMU shear wall on Grade beam.

    Were vertical bars extended from the foundation up into the wall with acceptable side clearance to develop them in tension? If so, can re-run your numbers using a modified reduced section to rule out crushing at the base. I would be more worried about minor axis bending if anything
