In addition to anchorage solutions provided by the SB and SSTB anchor bolts, the following table provides design options using the new PAB anchor bolts. These solutions may be used with Simpson Strong-Tie holdowns and are calculated per ACI 318 Appendix D. For special loads or footing geometries not addressed in the table below, the new PAB anchor bolts are also included in Simpson Strong-Tie Anchor Systems Anchor Designer ACI 318 software.

1. Anchorage designs conform to ACI 318 Appendix D and assume cracked concrete with no supplementary reinforcement.
2. Seismic indicates Seismic Design Category C through F. Detached one- and two-family dwellings in SDC C may use wind anchorage solutions. Seismic anchorage designs conform to ACI 318-05 Section D3.3.4.
3. Wind includes Sesmic Design Category A and B .
4. Foundation dimensions are for anchorage only. Foundation design (size and reinforcement) by Designer. The registered design professional may specify alternate embedment, footing size, and anchor bolt.
5. Allowable Stress Design (ASD) values are obtained by dividing Load Resistance Factor Design (LRFD) capacities by 1.43 for Seismic and 1.6 for Wind.

1. Plate washers are designed to develop the capacity of the bolt.

How to specify & order:
When calling out PAB anchor bolts, substitute the desired length for the “XX” in the Root Model Number.

So for a 5/8"x16 1/2" anchor bolt, the model number would be PAB5-16.5 (or PAB5H-16.5 for high strength).
