WARNING: JOISTS ARE UNSTABLE UNTIL BRACED LATERALLY
Storage
Bracing Includes: Blocking, Hangers, Rim Board, Sheathing, Rim Joist, Strut Lines
Lack of proper bracing during construction can result in serious accidents. Observe the following guidelines:
1. Properly install all blocking, hangers, rim boards, and rim joists at TJI® joist end supports.
2. Establish a permanent deck (sheathing), fastened to the first 4 feet of joists at the end of the bay or braced
end wall.
3. Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area and to each joist.
Store and handle joists in
vertical orientation.
4. Sheathing must be completely attached to each TJI® joist before additional loads can be placed on the system.
5. Ends of cantilevers require safety bracing on both the top and bottom flanges.
Protect products from

deformed-shank nails or other code-approved fasteners.
RECOMMENDED ADHESIVES
■ Adhesives must meet the requirements of
ASTM D3498 (AFG-01), and they must have a
minimum dry shear strength of 350 psi. For more
information, contact your iLevel representative.
Apply a 1⁄4" or larger bead of adhesive
At abutting panel edges, apply two 1⁄4" beads of adhesive
■ Fully nail floor panel within 10 minutes of applying adhesive (or
sooner if required by adhesive manufacturer).
■ Screws may be substituted for the nails noted above if the
screws have equivalent lateral load capacity.

(1) One row of fasteners permitted (two at abutting panel edges) for diaphragms. Stagger nails when using 4" on-center spacing and maintain 3⁄8"
joist and panel edge distance. For other applications, multiple rows of fasteners are permitted if the rows are offset at least 1⁄2" and staggered.
(2) Can be reduced to 4" on-center if nail penetration into the narrow edge is no more than 13⁄8" (to avoid splitting).
■ Recommended nailing is 12" on-center in field and 6" on-center

(1) All sheathing shall be properly blocked and nailed.
(2) Verify the lateral capacity of the wall. Not all types of code-allowed wall construction provide the same lateral resistance. Check with
your local building official or design professional.
(3) Detail A3.3 shall be a segmented wall, location of full-height structural sheathing per code.
(4) Sheathing shall be continuous over all plate-to-plate and plate-to-rim-board interfaces and may butt together at mid-depth of rim
board as shown in A3.4. At foundation, fasten the bottom edge of the sheathing to the sill plate.
(5) In addition, one 6'-8" standard door opening is allowed.
(6) If required, holdowns shall be Simpson Strong-Tie® CS20 (or equivalent) straps attached with four 8d (0.131" x 21⁄2") nails at each
end. As an alternative to holdown straps, wall sheathing may be attached as shown in A3.4. See footnote 4.

■ If necessary, increase filler and backer block height for face mount

hangers and maintain 1⁄8" gap at top of joist; see detail W on page 6.
■ Filler and backer block dimensions should accommodate required nail-
