See SSTB, page 33. Anchor types shown are made by others and used with Simpson Strong-Tie holdowns.
The design engineer may specify an alternate anchorage system, provided the anchor diameter is the same.

1. Anchor embedment length is based on a single-pour concrete foundation. Double pour
foundation systems, masonry walls and masonry footings must be evaluated by the designer.
2. Anchor bolt must be ASTM A307, A36 steel or better with hex head or nut washer nut, unless noted otherwise.
3. Spacing between anchors is 2l
e
minimum for anchors in tension at the same time.
4. Values assume no special inspection for 2500 psi concrete and no supplemental reinforcing
in the concrete failure area. For ACI 318-02, cracked concrete is assumed and ductility requirements
per D.3.3.4 not considered. Contact Simpson for other options.
5. 17380 for 1" and 18280 for 1 diameter with 3000 psi concrete and special inspection.
6. Requires a square or heavy hex head or nut minimum.
7. Requires an ASTM A449 type 1 or ASTM F1554 grade 55 anchor bolt and a heavy square nut or
x 1 x 1 min. plate washer.
