Steel Strong-Wall® Shearwalls: Garage Portal Systems on Concrete Foundations

Simpson Strong-Tie offers a Steel Strong-Wall® shearwall option for garage portal systems that combines simplified installation with superior performance.

  • Higher capacity with reduced concrete anchorage requirements (see Alternate Garage Front Options for other options)
  • Same anchor bolt template
  • Complete kit available to simplify the connection to the header or beam

Installation

Steel Strong-Wall® Portal Kit (SSWP-KT) Installation Instructions

  • Portal Frame Connection Kit is required to achieve increased load values listed for portal frame system.
  • SSWPS straps must be installed on exterior face of the Steel Strong-Wall® shearwall. Position header flush with exterior face of the Steel Strong-Wall shearwall.
  • 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 header is 7/8" using Simpson Strong-Tie® Strong-Drive® 1/4" x 3 1/2" SDS Heavy-Duty Connector screws.
  • Walls with 2x4 pre-attached studs may also be used in 2x6 wall framing. Install the wall flush to exterior face of the framing and add furring to the opposite side.
  • Walls may be installed with solid or multi-ply headers, see detail 11/SSW2

Garage Header Rough Opening Height

016a-2014

  1. The height of the garage curb above the garage slab is critical for rough header opening at garage return walls.
  2. Shims are not provided with Steel Strong-Wall®.
  3. Furring down garage header may be necessary for correct rough opening height.

Foundation Design (size and reinforcement) by Designer

  • This installation reflects lateral load requirements of a Single-Wall Portal System.*
  • It is the Designer’s responsibility to provide a complete load path for all loads in accordance with the governing codes.

Alternate Garage Front Options

These alternate garage front options may be used for applications when the Steel Strong-Wall® shearwall is installed at the full height (option 1) or without the additional Portal Frame Kit (option 2), when higher capacity or reduced concrete anchorage are not needed. Refer to the Standard Application on Concrete Foundations for product data and allowable load values.

For Garage Wall Option 2, the Designer shall design for:

  1. Shear transfer
  2. Out-of-plane loading effect
  3. Increased overturning and drift due to additional height
