roof details (continued)

2A

Beveled plate for slopes greater than ¼ :12.
Code-recognized connectors may be
substituted. For slopes greater than 4:12
connectors are required to resist lateral thrust.

Minimum attachment:

For slope ≤ ¼:12, one

10d box nail at each side of

bearing. For slope> ¼ :12

design joist attachment

to beveled plate to

transfer lateral

thrust.

Attached beveled plate
to framing with
one - 16d at 16" o.c.

2B

For roof slopes between ¼ :12 and 12:12,

provide a strap wrapped around

ridge beam

minimum unadjusted

uplift capacity of 300 pounds

unfactored resistance.

Bearing stiffeners required
when hanger does NOT
support I-Joist top flange

Application limited

to 4:12 pitch or less

Backer block: If top mounted
hanger is fully supported by top
flange, backer block only required on hanger side. If face nailing
is required, then install a backer block on the back side. Install
a backer block and filler block if a multiple I-joist is required. Nail
with ten -10d nails for flanges up to 1¼" wide. Use twelve-10d nails
for flanges wider than 1¼".

when end reaction exceeds
the "no stiffeners" factored
reaction resistances indicated
in this guide.

8d nails @ 6" o.c.- minimum

three-8d nails per blocking panel

(when used for lateral shear
transfer, match nail type and
sheathing edge nailing "boundary
nailing" for engineered
diaphragm applications)
Use minimum 8d nails.
