Strong-Wall® High-Strength Wood Shearwalls: Anchorage Solutions
WSWH-AB Anchor Bolts
WSWH-AB anchor bolts in 1" diameters offer flexibility to meet specific project demands. Inspection is easy; the head is stamped with a No-Equal® symbol for identification, bolt length, bolt diameter, and optional “HS” for “High-Strength” if specified.
Material: ASTM F1554 Grade 36; High-Strength (HS) ASTM A193 Grade B7
An additional nut for template installation is provided with each WSWH-AB.

WSWH-HSR Extension Kit
WSWH-HSR allows for anchorage in tall stemwall applications where full embedment of a WSWH-AB into the footing is required. The head is stamped for identification like a WSWH-AB. Kit includes ASTM A193 Grade B7 high-strength rod with heavy hex nut fixed in place and high-strength coupler nut.

Note: Do not use in place of WSWH-AB.

- Anchorage designs conform to ACI 318-14 Chapter 17 and ACI 318-11 Appendix D with no supplementary reinforcement for cracked and uncracked concrete as noted.
- Anchor strength indicates required grade of WSWH-AB anchor bolt. Standard (ASTM F1554 Grade 36) or high strength (HS) (ASTM A193 Grade B7).
- Seismic indicates Seismic Design Categories C through F. Detached one- and two-family dwellings in SDC C may use wind anchorage solutions. Seismic anchorage designs conform to ACI 318-14 Section 17.2.3.4.3 and ACI 318-11 Section D.3.3.4.
- Wind includes Seismic Design Categories A and B and detached one- and two-family dwellings in SDC C.
- Foundation dimensions are for anchorage only. Foundation design (size and reinforcement) by others. The registered design professional may specify alternative embedment, footing size or anchor bolt.
- Refer to slab on grade, curb, stemwall and interior footing details for W and de as shown below.
Foundation shear reinforcement to resist shear forces from Strong-Wall high-strength wood shearwalls located at the edge of concrete is shown in the table below. The WSWH12 used in wind applications does not require shear reinforcement when the panel design shear force is less than the anchorage allowable shear load shown in the table below.

- Shear anchorage designs conform to ACI 318-14 Chapter 17 and ACI 318-11 and assume minimum 2,500 psi concrete. See Tension Anchorage Solutions.
- Shear reinforcement is not required for interior foundation applications (panel installed away from edge of concrete), or braced wall panel applications.
- . Seismic indicates seismic design category C through F. Detached one- and two-family dwellings in SDC C may use wind anchorage solutions. Seismic shear reinforcement designs conform to ACI 318-14, section 17.2.3.5.3 and ACI 318-11 section D.3.3.5.
- .Wind includes seismic design category A and B and detached one- and two-family dwellings in SDC C.
- Additional ties may be required at garage curb or stemwall installations below anchor reinforcement per designer.
- Use (1) #3 hairpin for WSWH18 when standard strength anchor is used.
- Use (1) #3 tie for WSWH12 when panel design shear force exceeds tabulated anchorage allowable shear load.
- No. 4 grade 40 shear reinforcement may be substituted for WSWH shear anchorage solutions.
- Concrete edge distance for anchors must comply with ACI 318-14 section 17.7.2 and ACI 318-11 section D.8.2.
- The designer may specify alternate shear anchorage.
