Control Joints in Special Reinforced Masonry Shear Walls
Control Joints in Special Reinforced Masonry Shear Walls
(OP)
In the book Concrete Construction Engineering Handbook (edited by Edward G. Nawy) I found in Section 28.9.2.4 the statement:
"Due to the large quantities of prescriptive horizontal reinforcement, control joints are typically not necessary for special reinforced masonry shear walls"
Being relatively new to masonry design in high-seismic areas, I have no personal experience to draw upon. I've searched and found no similar statements made anywhere else. Does anyone have insight to offer?

Also try:
“Control Joints for Concrete Masonry Walls,”
NCMA TEK 10-2A, National Concrete Masonry
Association, Herndon, VA, 1998, 6 pp.
“Control Joints for Concrete Masonry Walls Empirical
Method,” NCMA TEK 10-2B, National Concrete
Masonry Association, Herndon, VA, 2005, 4 pp.
Although, I think it would be tough to find prescriptive measures to answer your question.
Hope that helps (a bit).

I suppose there are practical limits to consider. It might be helpful to the structure to have control joints at a reasonable spacing if your structural syetem can tolerate them.
