TITEN HD® Heavy Duty Screw Anchor for Concrete & Masonry
Tension and Shear Loads in Sand-Lightweight Concrete over Metal Deck
- The allowable loads listed are based on a safety factor of 4.0.
- Allowable tension loads for anchors installed in the concrete side may be increased 33 1/3% for short-term loading due to wind or seismic forces where permitted by code. Allowable shear loads for anchors installed through the metal deck side shall not be increased for wind or seismic forces.
- Allowable loads for anchors installed in the lower flute of the steel deck are for flutes with a trapezoidal profile with a depth of 3 inches, and a width varying from 4 1/2 inches at the bottom to 7 1/2 inches at the top. The spacing of the flutes is 12 inches. The metal deck must be minimum 20-gage with a minimum yield strength of 38 ksi and minimum ultimate strength of 45 ksi.
- Anchors may be installed off-center in the lower flute (up to 1 1/2" from the edge of the lower flute) without a load reduction.
- 100% of the allowable load is permitted at critical edge distance and critical spacing. Testing at smaller edge distances and spacings has not been performed.
