8" CMU wall with multiple 6" CMU courses around the buildng
8" CMU wall with multiple 6" CMU courses around the buildng
(OP)
Architect is showing a 6" CMU course at multiple locations in an 8" CMU wall so that it creates an architectural band (reveal) around the buiding perimeter.
Does anyone know where I can find out how to address this in ACI 530? Or any other document or article that can help me determine if this is actually allowed and how to adjust the wall reinforcing accordingly.
thanks.

If anyone uses Enercalc, I did notice in the masonry wall module, you can input a reveal distance and height, and it shows the picture with the block inset and the reinforcing lapped.

How high is the wall? Very possibly it could be a 6" structural wall with courses of 8" block (bond beams or filled top units) used as projections beyond the face of the 6" block. 6" block can carry large loads and the 8" can be minor elements if the architect is knowledgeable. - There I go again about attacking the U.S. tradition of using low (assumed minimal) strength 8" units with no accepatance standards.

Only thing mentioned in ACI 530 for reinforced masonry is to desgin by one of the design chapters. Reinforced masonry doesn't appear to be limited in the amount of corbelling per course the way unreinforced is. Just needs to be stable and meet design requirements.
