Raised Floor (-RF) walls are designed and tested for installation on top of raised wood floor systems. All 2nd Floor Applications must use the Raised Floor Models. Raised Floor walls are compatible with both solid sawn lumber and I-joist floor systems. Simpson SDS screws pre-installed in both the top and bottom of the wall allow for fast installation to the top plate and floor framing elements.

Raised Floor walls are code listed for use on the second floor of two-story wood light-frame construction. Simpson Strong-Tie recommends the Simpson Takeup Device, (SW-TUD1KT), be used at the 2nd floor to compensate for wood shrinkage and settlement due to dead load.

First-story walls of a two-story application may be either Standard or Raised Floor walls.

1. For two-pour applications, use SSTB34. See SSTB anchor bolts for allowable loads and installation. Alternate 7/8" diameter anchorage may be required depending on load for two-story applications.
2. All thread rod not supplied with Raised Floor walls. Minimum ASTM A36 required. Engineer of record must specify if high strength all-thread rod is required, depending on load.

Naming Scheme:

• 1997 UBC & 2000/2003/2006 IBC Allowable Shear & Drift Values (PDF)
• Allowable Vertical Loads and Out-of-Plane Loads for Wood Strong-Wall (PDF)

Load tables list values based upon results from the most recent testing and/or calculations and may not match those in current code reports. Where code jurisdictions apply, consult the current reports for applicable load values.
