(This section is specifically about SSTB Anchor Bolts for Wood Strong-Wall in concrete foundations. For other applications, see the full SSTB Anchor Bolt page.)

The SSTB is designed for maximum performance as an anchor bolt for holdowns and Wood Strong-Wall® shearwalls. Extensive SSTB testing has been done to determine the design load capacity in common applications. Design loads are based on testing performed to the requirements of ICC-ES Acceptance Criteria AC 399. The SSTB is code listed by ICC-ES under the 2006 and 2009 IBC and IRC (ICC-ES ESR-2611).

SSTB28

SSTB28L

Special Features :

• Innovative offset angle reduces side blowout and provides more concrete cover
• Embedment line on the shank and installation angle on the head help ensure correct installation
• Head stamp includes length and the "No Equal" sign (≠) for easier inspection after the pour
• Unique shape results in less rebar interference.

Material: ASTM F1554, Grade 33

Finish: None. May be ordered HDG; contact Simpson Strong-Tie.

Installation:

• SSTB solutions shown here are for monolithic slab-on-grade installations. For stemwall, concrete block and two-pour installations refer to the full SSTB anchor bolt webpage
• Nuts and washers are not supplied with the SSTB; install standard nuts, couplers and/or washers as required.
• On HDG SSTB anchors, chase the threads to use standard nuts or couplers or use overtapped products in accordance with ASTM A563 (Simpson NUT7/8-OST or CNW7/8-7/8OST).

Reinforced Concrete Foundation

• Anchor bolt templates are recommended and are required in some jurisdictions.
• Install the SSTB per plan view detail shown on this page. Install one #4 rebar 3" to 5" (may be foundation rebar not post-tension cable) from the top of the foundation.
• The SSTB does not need to be tied to the rebar.
• Minimum concrete compression strength is 2500 psi. Unless noted otherwise, no special inspection is required for foundation concrete when the structural design is based on concrete strength no greater than 2500 psi (IBC Section 1704.4).
• Unless otherwise noted, do NOT install where: (a) a horizontal cold joint exists within the embedment depth between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load; or (b) slabs are poured over concrete block foundation walls.

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 uplift force is less than the allowable SSTB load.
   
3. SW18x8/9, SW24x8/9, SW32x9, SW48x8/9/10 under seismic loading may use SSTB28 with no load reductions. Maximum uplift for all other models shall be limited to 10,460 lbs (Wind and SDC A&B), and 8,785 lbs (SDC C-F).
