diaphragm-action decks. Indicate cellular deck to
be used as wiring raceways on the project drawings
if included below.
NOTE: The designer must determine if there are
shoring requirements for composite decks. For most
applications the design is selected so that shoring
is not required. Shoring requirements shall be
detailed on the design drawings.
**************************************************************************
Install steel deck units in accordance with [SDI 30][SDI DDM02 and]
approved shop drawings. Place units on structural supports, properly
adjusted, leveled, and aligned at right angles to supports before
permanently securing in place. Damaged deck and accessories including
material which is permanently stained or contaminated, deformed, or with
burned holes shall not be installed. Extend deck units over three or more
supports unless absolutely impractical. Report inaccuracies in alignment
or leveling to the Contracting Officer and make necessary corrections
before permanently anchoring deck units. Locate deck ends over supports
only. [Ends of floor deck may be lapped or butted.] Do not use unanchored
deck units as a work or storage platform. [Do not fill unanchored deck with
concrete.] Permanently anchor units placed by the end of each working day.
Do not support suspended ceilings, light fixtures, ducts, utilities, or
other loads by steel deck unless indicated. Loads shall be distributed by
appropriate means to prevent damage. [Shoring shall be in position before
concrete placement begins in composite or form deck. ][Size cellular
decking provided as electrical raceways to accommodate indicated wiring
systems. Chip off burrs and eliminate sharp edges which may damage wiring.
Mesh decking panels accurately and place in accordance with UL 209.]
[Acoustical material shall be neatly fitted into the rib voids.]

NOTE: Use of powder actuated or pneumatically
driven fasteners is limited to Seismic Zone 1 and
areas with wind design velocity of less than 160 km/h
100 mph. However, based upon the submittal of
supporting calculations and data to substantiate
that such fasteners can resist the design loads, and
approval of the Contracting Officer, fasteners may
be used in all seismic areas and in areas with the
wind velocity to 160 km/hr (100 mph) or more. Refer
to COE Technical Instruction (TI) 809-04, "Seismic
Design for Buildings".

NOTE: Refer to UFC 1-200-01 for shear capacity,
flexibility, connection details, size and spacing of
welds and attachments, and concrete fill
requirements.
For diaphragm acting decks, refer to Steel Deck
Institute's "Diaphragm Design Manual" (First and
Second Editions).
