Strong -Wall Shear Panel Replacing a 4 -ft Braced Wall Panel
Dear Mr. Miller:
This letter addresses the use of a SW24x10 -RF or SW 18x9 -RF to replace a 4 -ft braced wall panel as described in
Section R602.10 of the 2006 International Residential Code. It is my understanding that these panels will be used in
the second story of this project with a site -built wood -framed wall with a post below. This application is covered in
sections 4.1.3 and 4.2.2 of our ICC -ES evaluation report ESR -1267.
Detailed information on the use and installation of our Strong -Wall panels to replace prescriptive braced wall panels
is contained in our Strong -Wall Shearwalls Prescriptive Design Guide, T- SWPDG10. This includes pre - engineered
foundation anchorage. However, the application described above is not listed in the wall selection tables on pages 22-
28.
Simpson Strong -Tie has evaluated this application and anchorage. The wall selection and corresponding Anchor
Classification may be determined using the First - Story -On- Wood -Floor Application table on page 23 under the
Single -Story Application column. Both wall sizes result in an Anchor Classification of B. This classification into a
concrete stemwall is described on page 65.
The post below each end of each Strong -Wall panel must be a minimum 3 -ply 2x4.
Please contact me with any questions, comments, or concerns. Refer to T- SWPDG10 for additional important
information.
Sincerely,
Shane Vilasineekul
Branch Engineering Manager
