ACI 530 requires that masonry columns utilize a minimum of (4) vertical bars. However, it's common practice to use CMU filled cells as the vertical support at masonry openings. For example, imagine a corner condition where two beams are supported by (1) 1'-4" x 1'-4" x 8" CMU L-Shaped corner, fully grouted with (1) vertical bar in each cell (3 cells total).
Assuming those filled cells take the axial load and lateral wind from the attached fenestration, how does the (4) bar requirement get resolved. I've seen this in many corner conditions where the GC doesn't want to CIP.
Is that analysis based on the combined axial and lateral for a 16" wide strip of 8" CMU that is fully grouted? Is there any software to design these different arrangements?
