The specified transverse wall loadings will
represent the maximum design wind loading for
cladding and the maximum design seismic loading for
building components as determined from ASCE 7and TI
809-04, respectively. Lateral loadings are applied
normal to the wall and should be specified in
detail, differentiating positive (inward) and
negative (outward) loading directions and
intensities and indicating, separately, loadings for
specific wall areas which are subjected to increased
design loadings, such as building corners,
additional stories, parapets, etc.

Cold-formed framing shall consist of steel studs, top and bottom tracks,
runners, horizontal bridging, and other cold-formed members and other
accessories. All members and components made of sheet steel shall be
hot-dip galvanized in accordance with ASTM A 653/A 653M with a minimum
coating thickness of G 60. Framing covered herein shall be used only in
framing the exterior masonry veneer steel stud wall system as indicated on
the detail drawings. Metal framing for interior partitions are specified
in Section 09100 METAL SUPPORT ASSEMBLIES. Metal framing for [_____] is
specified in Section [_____].
2.4.1
Steel Studs
**************************************************************************
NOTE: The minimum depth of the steel stud will be
89 mm (3-1/2 inches), the minimum flange width will
be 35 mm (1-3/8 inches) and will have a minimum
return lip on the flange of 6 mm (1/4 inches). The
actual required stud depth, thickness, grade and
spacing should be determined prior to the completion
of contract documents. Use larger studs only if
needed to resist design loadings or to provide space
for wall insulation.
**************************************************************************
Studs shall be furnished as shown in the contract drawings.
