Steel Strong-Wall® Shearwalls: Installation of Two-Story Stacked on Concrete Foundations

  • Do not cut the Steel Strong-Wall® or enlarge existing holes, doing so will compromise the performance of the wall.
  • Do not use an impact wrench to tighten nuts on the anchor bolts.
  • Maximum shim thickness between the Steel Strong-Wall and top plates is 7/8" using Simpson Strong-Tie® Strong-Drive® 1/4"x3 1/2" SDS Heavy-Duty Connector screws. For additional shim thicknesses, see detail 5/SSW2 and detail 9/SSW2.
