Wood Strong-Wall® Shearwalls
SSTB® Anchor Bolts
Now the most economical anchorage solution for our Wood Strong-Wall®
shearwall is also code listed under the latest I-codes. The unique design
of the SSTB anchor bolt allows for smaller footings that require less
concrete. Additionally, the SSTB has been tested in the most common
Wood Strong-Wall foundation applications for use in all seismic design
categories and high-wind regions, so it is easier to specify than ever.

1. This table applies to single story Wood Strong-Wall applications directly on
concrete. Two-story stacked applications may require high-strength anchors
(designed by others).
2. Additional applications may use the SSTB where the demand anchor tension
force is less than the allowable SSTB load shown in ICC-ES ESR-2611.
3. SW18x8/9, SW24x8/9, SW32x9, SW48x8/9/10 under seismic loading may use
SSTB28 with no load reductions. Maximum anchor tension force for all other
models shall be limited to 10,460 lbs (Wind and SDC A&B), and
8,785 lbs. (SDC C-F).
