Horizontal Reinforcement in CMU Retaining Wall Stem
Horizontal Reinforcement in CMU Retaining Wall Stem
(OP)
Im designing a cantilevered retaining wall and I am not sure if I should specify any horizontal reinforcement in the stem. Stem will be 8" CMU with No. 6 bars at 32" O.C. With standard masonry wall construction you have your horizontal wires usually at every other course with a tie-beam or bond beam at the top of the wall. I dont expect any lateral loads from the ends of the retaining wall; all the calcs check out for sliding, overturning, bearing, and stresses in the stem from the lateral soil loads. I didn't see anything in the ACI specifically for this either but I could be missing something. Any thoughts?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Why would you use two in one course? That will just make fully grouting the wall more difficult.

And regarding fully grouted, I thought that being fully grouted was a requirement for any CMU below grade.

So if it is fully grouted, would you still group the bars, or distribute them?
