Including Change 2, August 2006
All weld metal and base metal subjected to cyclic tension must be
supplied with "charpy" V-notch testing in accordance with ASTM A6 supplementary
requirement SS. (5 specimen option). The impact test must meet a minimum average
value of 27.1 Joules (20 ft-lbs) absorbed energy at 18 degrees C (0 degrees F).
Unless otherwise noted herein, all steel joist design and construction must be in
accordance with UFC 1-200-01.
Unless otherwise noted herein, all steel deck design and construction
must be in accordance with UFC 1-200-01.
Steel form decks must be a minimum of 0.378mm (0.149 inches -28 gage)
thick. Roof and composite decks must be a minimum 0.909 mm (0.0358 inches 20
At a minimum, all steel deck must be galvanized in accordance with ASTM
A 653/653M G60 specifications. For steel deck exposed to spray from salt, salt water,
brackish water, or seawater provide ASTM A 653/653M G90 galvanizing.
Cold-Formed Steel Framing.
Unless otherwise noted herein, all cold-formed steel framing design and
construction must be in accordance with UFC 1-200-01.
Design using cold-formed steel studs and joists must comply with material
specifications, nomenclature, section properties, and load tables found in SSMA
Product Technical information.
Minimum thickness of cold-formed steel framing members to be welded
must be 1.44 mm (0.0566 inches 16 gage) thick.
All cold-formed steel-framed walls must be anchored to foundations with
galvanized anchors as needed to resist the design forces. Anchors for exterior walls,
interior load-bearing walls, and shear walls must not be less than 12.7mm (1/2 inch)
diameter embedded anchor bolts, expansion bolts, or adhesive anchor system with
101mm (4 inches) embedment spaced a maximum of 1219mm (48 inches) on center.
Anchors for interior non-bearing, non-shearwall partitions must not be less than 10mm
(3/8 inch) diameter embedded anchor bolts, expansion anchors, or adhesive anchor
systems with 101mm (4 inch) embedment spaced a maximum of 1219mm (48 inches)
on center, or with 3.7mm (0.145 inch) diameter powder-actuated fasteners spaced at
610mm (24 inches) on center.
Cold-formed steel members must be connected with screw fasteners or by
welding. The use of "pneumatic nailing" is not permitted.
