(1) Exterior wood framed walls and all wood framed shear walls
(interior or exterior) shall be anchored to concrete foundations with "
round embedded anchor bolts (w/ 4" embedment) spaced 30 inches on
center.
(2) Interior non-bearing, non-shear wall partitions may be anchored with 3/8"
round embedded anchor bolts (w/ 3"embedment) or 3/8" round expansion
anchors (with 4" embedment) spaced a maximum of 48" on center. As an
alternate, 0.145 " diameter powder actuated fasteners may be used at a
maximum spacing of 24" on center.
6.8.8.4
Cold Formed Metal framing
Welding of light gage cold formed material is permitted for 16 gage and greater
thicknesses. Designs for this material shall be based on well established allowable force
values for welds and mechanical fasteners. Light gage steel stud wall systems shall be
anchored to concrete foundations to resist design lateral loads with minimum anchorage
as follows:
a. Exterior walls and all walls designed as shear walls to have " round
embedded anchor bolts (with 4" embedment) spaced a maximum of 30" on
center.
b. Interior bearing walls to have " round embedded anchor bolts (with 4"
embedment) spaced a maximum of 30" on center.
c. Interior non-bearing, non-shearwall partitions to have 3/8" round embedded
anchor bolts (with 3" embedment) or 3/8" round expansion anchors (with 4"
embedment) spaced a maximum of 48" on center. As an alternate, 0.145 inch
diameter powder actuated fasteners may be used at a maximum spacing of 24" on
center.
6.8.8.5 Steel Framing
Project documents shall call for one class of structural steel bolt throughout the entire
project. For example, ASTM A307 or ASTM A325 for all connections. The locations of
slip critical (friction) bolts must be clearly defined. Anchor bolts and other threaded
material may differ from the standard bolts.

Steel Roof Deck
Steel deck diaphragms must be welded along the side seams. Button punched seams are
not permitted.
