Tension Loads for Carbon-Steel Wedge-All (and Tie-Wire) Anchors in Sand-Lightweight Concrete over Metal Deck

1. The allowable loads listed are based on a safety factor of 4.0.
2. For installations in concrete (not through metal deck), allowable loads may be increased by 33 1/3% for short-term loading due to wind or seismic forces.
3. For installations through metal deck, allowable Tension loads must be decreased 23% and allowable Shear loads may be increased 33 1/3% for short-term loading due to wind or seismic forces.
4. Refer to allowable load adjustment factors for edge distance.
5. 100% of the allowable load is permitted at Critical Spacing. Loads at reduced spacing have not been determined.
6. Drill bit diameter used in base material corresponds to nominal anchor diameter.
7. The minimum concrete thickness is 1 1/2 times the embedment depth.
8. Metal deck must be minimum 20 gauge.
