Tension Load Shear Load Concrete Block (CMU)
Tension and Shear Loads for Carbon Steel Wedge-All Anchors in Grout Filled CMU (Anchor Installed in Horizontal Mortar Joint or Face Shell)
  1. The tabulated allowable loads are based on a safety factor of 5.0 for installations under the IBC and IRC. For installations under the UBC use a safety factor of 4.0 (multiply the tabulated allowable loads by 1.25).
  2. Listed loads may be applied to installations on the face of the CMU wall at least 1 1/4 inch away from headjoints.
  3. Values are for 8-inch-wide CMU Grade N, Type ll, lightweight, medium-weight and normal-weight concrete masonry units conforming to UBC Standard 21-4 or ASTM C90. The masonry units must be fully grouted with grout complying with UBC Section 2103.4 or IBC Section 2103.12. Mortar must be Type M or S prepared in accordance with Section 2103.3 of the UBC and UBC Standard 21-15, or IBC Section 2103.8. The specified compressive strength of masonry, f'm, at 28 days must be a minimum of 1,500 psi.
  4. Embedment depth is measured from the outside face of the concrete masonry unit.
  5. Drill bit diameter used in base material corresponds to nominal anchor diameter.
  6. Allowable loads may be increased by 33 1/3 percent for short-term loading due to wind and seismic forces.
  7. Tension and Shear loads for the Wedge-All anchor may be combined using the parabolic interaction equation (n=5/3).
  8. Refer to allowable load adjustment factors for edge distance.
