  1. The allowable loads are based on a safety factor of 4.0.
  2. The minimum concrete thickness is 1 1/2 times the embedment depth.
  3. Tension and Shear loads may be combined using the straight line interaction equation (n=1).

Tension and Shear Loads in 8-inch Lightweight, Medium-Weight and Normal-Weight Hollow CMU

122d-2012
  1. The tabulated allowable loads are based on a safety factor of 5.0 for installations under the IBC and IRC.
  2. Values for 8-inch wide, lightweight, medium-weight, and normal-weight CMU.
  3. The minimum specified compressive strength of masonry, f'c, at 28 days is 1,500 psi.
  4. Embedment depth is measured from the outside face of the concrete masonry unit and is based on the anchor being embedded an additional 1/4" through the 1 1/4" thick face shell.
  5. Allowable loads may not be increased for short-term loading due to wind or seismic forces. CMU wall design must satisfy applicable design standards and be capable of withstanding applied loads.
  6. Set drill to rotation-only mode when drilling into hollow CMU.
  7. Do not use impact wrenches to install in hollow CMU.
