Strong-Wall® Bracing Selector: Design Example
The Strong-Wall Bracing Selector (SWBS) provides pre-engineered Strong-Wall alternatives to code-prescribed braced wall panels. Strong-Wall model numbers and foundation anchorage designs are determined to meet job specific requirements and provide the narrowest bracing solutions possible. This app can be used with the Wall-Bracing-Length Calculator: Start with the WBLC to determine wall bracing length requirements then export project information and bracing requirements to the SWBS.

Design Example
Design Criteria
- 2012 IRC
- Basic Wind Speed - 90 mph, Exposure Category B
- Seismic Design Category B
- 3 Braced-Wall Lines at 10' and 19'
- 8' Eave-to-ridge height
- 8" wide concrete stemwall, f'c = 2500 psi
Step 1 – Enter Project Information
- Identify Braced-Wall Line of interest and note total length of bracing required per IRC using the Wall-Bracing-Length Calculator.
Braced-Wall Line 1:
Garage Front - First Story
Second Story Wall Bracing constructed in accordance with the IRC
- Total Length of Bracing Required = 4.6 ft
- Total Length of qualifying bracing = 0 ft
- Remaining Length of Bracing Required = 4.6 ft
Step 2 – Enter Project Inputs
- Jobsite Category: Wind
Jobsite Category automatically chosen if using Wall-Bracing-Length Calculator first then launching Strong-Wall Bracing Selector
- Application: Garage Front - 1st of 2 Story
- Foundation Type: Concrete Stemwall - Anchor into Wall
- Foundation Strength: 2500 psi
- First Story Wall Height: 8 ft with Header on Top
Step 3 - Enter Strong-Wall Information
- Strong-Wall Type: Steel Strong-Wall
- Portal Kit: Selected
- Available Wall Space: 24 in
- Strong-Wall Location:
Option 1: Garage - Single Panel
Use single Strong-Wall garage portal system at garage front. Solution based on 6 ft of contributing wall bracing length.
Option 2: Garage - Double Panel
Use double Strong-Wall garage portal system at garage front to reduce anchorage requirements and provide narrower wall bracing solution.
Available Solutions Summary
Option 1: Garage - Single Panel
- SSW15x8 w/SSWP-KT
- Anchored with SB1 × 30 (le = 24"). No Adhesive anchorage solutions available for the option.
Option 2: Garage - Double Panel
- Two SSW12x8 w/SSWP-KT
- Anchored with SSWAB3/4 × 30 (le = 20") or, 3/4" diameter adhesive anchor with 12" embedment using Simpson Strong-Tie SET-3G™ or AT-XP&trade adhesive.
For additional Braced-Wall Lines, repeat Steps 1-3.
