If you were making a triangular CMU wall, would the bond beam still be at the top? How do they accomplish this with the cutting and sloping of the bond beam?
Here's a job I worked on with this case - they neatly cut the blocks and laid a steel layer in the top course
Our walls are always fully filled/reinforced though so the detailing wasn't super critical
On older buildings that are partially filled I've typically seen it like (a) in Pham's details, and usually that is poured as solid insitu concrete rather than masonry
