NCMA Solutions Center: Is there any guidance available for crack control in high seismic areas for concrete masonry walls?

Yes. The “Engineered Method” is a method that was developed to provide a rational approach to crack control, particularly for high seismic areas. The engineered method uses a Crack Control Coefficient (CCC) which indicates anticipated wall movement, and is determined based on mix design of units, production, and curing methods. For more information on crack control using the engineered method, see TEK 10-3Control Joints for Concrete Masonry Walls – Alternative Engineered Method.
