FWAZ/FWANZ Foundation Wall Angle

FWA foundation anchors connect the foundation or basement walls to the floor system to resist out-of-plane forces imposed by soil pressure. The FWAZ attaches through the mudsill into the foundation using the Simpson Strong-Tie® Titen HD® heavy-duty screw anchor, eliminating the need for separate anchor bolts into the rim joist. The new FWANZ fastens to the mudsill with nails, relying on other anchorage (by Designer) to anchor the rim joist to the foundation. The spacing of the FWA anchors is independent of the joist spacing, allowing for a multitude of options based on soil pressures.

Special Features:

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 IBC and Section R404 in the IRC.
Eliminates the need of costly cantilevered foundation designs.

Material: 14 gauge

Finish: ZMAX® coating. See Corrosion Information.

Installation:

Use all specified fasteners. See General Notes.
Connectors must be fastened directly to the outside face of the rim board with 5-10dx1 1/2 (0.148" dia. x 1 1/2") long nails.
Connectors must be located within 5" of adjacent joist/blocking for floor joist spacings larger than 16" 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 2006 IRC Section R404.1.
Splice joint not permitted on rim board in same bay unless blocking is placed on both sides of the splice. The maximum sill plate thickness to be used for the FWAZ only shall be 1 1/2".
FWAZ only – must be anchored to the foundation wall with 5/8"x6" mechanically galvanized Titen HD anchor (included). Cast-in-place anchor bolts may not be used as a substitute.
Splice joint not permitted on rim board in same bay as FWANZ unless blocking is placed on both sides of the splice joist.
When I-joist rim material is used, backer blocks must be used. Installed per manufacturer’s recommendations.

1. Lateral (F₂) loads are based on load duration factor C_D = 0.90 with no further increase allowed.
FWAZ spacing shall be per Designer.
FWAZ must be located within 5" of adjacent joist/blocking for floor joist spacings larger than 16" o.c. and may be centered between joists/blocking for 16" o.c. floor joist spacing.
Maximum sill plate thickness shall be 1 1/2".
The Titen HD anchor used in the FWAZ to resist the out-of-plane (F₂) forces may also be used to resist in-plane shear forces provided the Designer determines the Titen HD anchor allowable loads (refer to Simpson Strong-Tie Anchor Systems® website for complete information) and evaluates the combined loading condition with the published F₂ loads.
NAILS: 10dx1 1/2= 0.148" dia. x 1 1/2" long. See other nail sizes and information.

FWANZ may be used to transfer F₁ loads up to 310 lbs. No further increase in load permitted.
For simultaneous F₁ and F₂ loads, the connector must be evaluated using the unity equation (see Instructions for the Designer, note e).
Designer shall evaluate rim board and sill plate design based on demand load.
FWANZ spacing and sill plate anchorage to be specified by the Designer.
For joist/blocking spacing greater than 16" o.c. the FWANZ must be located within 5" o.c. of the adjacent joist/blocking.
When floor joists are parallel to the rimboard, Designer must ensure proper load transfer from rimboard into diaphragm.
Values based on a load duration factor C_D = 0.90.
NAILS: 10dx1 1/2= 0.148" dia. x 1 1/2" long. See other nail sizes and information.

On-Center Spacing Requirements for FWAZ

Table values are based on 1 1/4" thick 1.3E TimberStrand® LSL rim board material. Contact Simpson for spacings using alternate rim board material.
Dashed cells indicate FWAZ not required. Joist/blocking connection shall be Type A per 2006 IRC Table R404.1(1) and anchor bolt spacing per 2006 IRC Table R404.1(2).
Soil classes are in accordance with Unified Soil Classification System (Table R405.1 of 2006 IRC and Table 1610.1 of 2006 IBC).
Spacing tables address the top reaction and prescriptive support for foundation walls in section R404.1 of the 2006 IRC. See 2006 IRC, Chapter 4, Foundations for additional requirements.
