Final answer:
The center-to-center spacing of vertical reinforcement in a CMU wall cannot be less than 8 inches.
Step-by-step explanation:
The statement in the question is true. The center-to-center spacing of vertical reinforcement in a CMU (Concrete Masonry Unit) wall cannot be less than 8 inches.
This spacing requirement is due to the need for proper structural integrity and strength of the wall. Reinforcement helps resist forces like bending or shear and prevents the wall from failing.
By ensuring a minimum center-to-center spacing of 8 inches, the reinforcement is adequately distributed across the wall, providing the necessary support and durability to the CMU wall construction.
