FWA Foundation Wall Angle
On This Page
The FWANZ foundation anchor connects the foundation or basement wall to the floor system to resist out-of-plane forces imposed by soil pressure. The foundation wall angle fastens to the mudsill with nails, relying on other anchorage (by designer) to anchor the sill plate to the foundation.
- Compatible with solid sawn joists, I-joists and floor trusses
- Testing performed on most common rim materials and types
- Addresses design needs set forth in Section 1610.1 in the 2015 / 2018 / 2021 IBC and Section R404.1 in the 2015 / 2018 / 2021 IRC
- Eliminates the need of costly cantilevered foundation designs
- 14 gauge
- ZMAX® coating; see Corrosion Information
- Use all specified fasteners; see General Notes.
- Connector must be fastened directly to the outside face of the rim board with (5) 0.148" x 1 1/2" long nails.
- Connector must be located within 4" of adjacent joist/blocking for floor joist spacing up to 48" o.c. and may be centered between joists/blocking for 16" o.c. floor joist spacing.
- When floor joists are parallel to the rim board, full depth blocking shall be used in the first two bays of the floor per 2012 / 2015 / 2018 / 2021 IRC Section R404.1.
- Splice joint not permitted on rim board in same bay unless blocking is placed on both sides of the splice.
- When I-joist rim material is used, backer blocks must be used. Installed per manufacturer’s recommendations.
These products are available with additional corrosion protection.
- FWANZ may be used to transfer F1 loads up to 260 lb. No further increase in load permitted.
- For simultaneous loads in more than one direction, the connector must be evaluated using the Unity Equation, as described in General Instructions for the Designer.
- Designer shall evaluate rim board and sill plate design based on demand load.
- FWANZ spacing and sill plate anchorage are to be specified by the designer.
- When floor joists are parallel to the rim board, designer must ensure proper load transfer from the rim board into the diaphragm.
- Values are based on a load duration factor of CD = 0.90.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
