Structural
2.0 USES
The ShortSpan DGS (drywall grid system) described in this
report is used as a ceiling framing system for screwattached gypsum panel products in interior applications, in
nonfire-resistance-rated construction.
3.0 DESCRIPTION
3.1 General:
The ShortSpan DGS (drywall grid system) is a ceiling
framing system that extends from wall to wall, and provides
support for screw-attached gypsum boards. The system
consists of tees that extend from wall to wall, and are
supported on angle moldings that are attached to gypsum
wallboard–faced steel wall framing. Supports for tees are
provided by StrongBack Supports or QuikStix Locking
Pocket Mains, which are attached to supporting
construction using QuikStix Uptight Clips.
3.2.3 StrongBack Support: The StrongBack support
measures 2 inches (51 mm) high, and is notched along
the bottom edge at 8 inches (203 mm) on center to
allow connections with ShortSpan Tees. The steel used to
form the StrongBack support complies with ASTM A568
Designation 1008 or 1010, and has a minimum G40
galvanization coating designation in accordance with
ASTM A653. Table 1 and Figure 1 specify the part
numbers, dimensions and lengths.
3.2.4 QuikStix Locking Pocket Main: The QuikStix
Locking Pocket Main member has an inverted T-shape,
and locking tabs punched into the bottom flanges at
8 inches (203 mm) on center. The steel used to form the
members complies with ASTM A568 Designation 1010,
and has a minimum G40 galvanization coating designation
in accordance with ASTM A653. Table 1 and Figure 1
specify the part numbers, dimensions and lengths.
3.2.5 Quikstix Uptight Clip: The QuikStix Uptight Clip is
a 1.75-inch-wide (44.4 m) L-shaped clip, with a 1.42-inch
(36 mm) short leg and a 4.42-inch (112 mm) long leg. The
clip is used to fasten StrongBack Support members and
QuikStix Locking Pocket Main members to structural
support members. The steel used to form the QuikStix
Uptight Clip complies with ASTM A568 Designation 1008
or 1010, and has a G90 galvanization coating designation
in accordance with ASTM A653.
3.2 Components:
3.2.6 Gypsum Board: Gypsum panel products must
comply with ASTM C36 or C1396, and must have a
maximum thickness of 5/8 inch (15.9 mm) and a maximum
2
weight of 2.5 pounds per square foot (12.3 kg/m ).
3.2.1 ShortSpan Tee: The ShortSpan Tee has an
inverted T-shape, a rotary-stitched double web and a
knurled lower flange that has a reverse hem along the
entire length of the bottom flange. The steel used to form
the tee complies with ASTM A568 Designation 1010, and
has a minimum G40 galvanization coating designation in
3.2.7 Screws: Screws used to fasten angle moldings to
framing, and QuikStix Uptight Clips to tees, StrongBack
1
or QSLPM members, must be No. 8 by 1 /4-inch-long
(32 mm), wafer-head, steel-framing, self-drilling tapping
screws complying with SAE J78 and ASTM C1002, and
must be recognized in a current ICC-ES evaluation report.

4.0 DESIGN AND INSTALLATION
4.1 Design:
The ceiling assembly is designed to support one layer of
5
/8-inch-thick (15.9 mm) gypsum board having a maximum
2
weight of 2.5 psf (12.3 kg/m ). Since the ShortSpan DGS
system consists of gypsum boards screwed to suspended
framing members, and the ceiling is supported on one level
extending between laterally braced walls, the ShortSpan
DGS system is not within the scope of the lateral load
design requirements of ASTM E580 (for the 2012 IBC and
ASCE 7-10) and CISCA 3-4 (for the 2009 and 2006 IBC
and ASCE 7-05). Therefore, the ShortSpan DGS system
must be designed for seismic loads as required under
Chapter 13 of ASCE 7.
4.2 Installation:
4.2.1 General: The ceiling system must be installed in
accordance with this report and the manufacturer’s
published installation instructions.
4.2.2 Angle Moldings: The angle moldings must be
screw-attached to No. 25 or No. 20 gage steel wall studs
spaced a maximum of 24 inches (610 mm) on center, with
1
the No. 8 by 1 /4-inch-long (32 mm), wafer-head, steelframing, self-drilling tapping screws described in Section
3.2.7.
4.2.3 ShortSpan Tees: ShortSpan Tees must be
installed to span between angle moldings or QuickStix
Locking Pocket Main members, as applicable. The tees
1
must be cut within /8 inch (3.2 mm) of the vertical leg of
the molding, and both ends must be fixed in the locking
tabs of either the Angle Moldings or the QuickStix Locking
Pocket Main members. ShortSpan Tees must be installed
at a maximum of 16 inches (406 mm) on center, and
1
leveled to within /4 inch in 10 feet (6.4 mm in 3048 mm).
The maximum length of tees between bearing end
supports is 14 feet (4 267 mm), and must be based on
the length of the tees, as noted in Table 1. The
maximum unsupported length between clips, hanger
wires or QuickStix Locking Pocket Main members is 7 feet
(2.13 m).
4.2.4 StrongBack Support: When used, the StrongBack
support must be installed by opening the lock tabs and
sliding the support over the bulb of the ShortSpan Tees,
then closing the lock tab to the original position. The
StrongBack support must be leveled to within 1/4 inch in
10 feet (6.4 mm in 3048 mm). Vertical supports for the
StrongBack Support that consist of vertical hangers and
perimeter hangers must be designed and installed in
accordance with the code. The maximum span of the
StrongBack support between vertical supports is 36 inches
(914 mm).
4.2.5 QuickStix Locking Pocket Mains (QSLPM): When
used, the QuickStix Locking Pocket Main members must
be installed parallel to the braced walls. The members
must be cut within 1/8 inch (3.2 mm) of the vertical leg of
the end supports, and both ends must be fixed in the
locking tabs. ShortSpan Tees must be installed as
described in Section 4.2.3. Vertical supports for the
QSLPM members that consist of vertical hangers and
perimeter hangers must be designed and installed in
accordance with the code. The maximum span of a
QSLPM member between vertical supports is 36 inches
(914 mm).
4.2.6 Quikstix Uptight Clip: When used, the QuikStix
Uptight Clip must be fastened to StrongBack and QuickStix
Locking Pocket Main members, as applicable, at a
maximum spacing of 36 inches (914 mm) on center, with
Page 2 of 4
four of the No. 8 by 11/4-inch-long (32 mm), wafer-head,
steel-framing, self-drilling tapping screws described in
Section 3.2.7. Attachment of the QuikStix Uptight Clip must
be with the short offset radius end of the clip facing the
member, to allow correct alignment between the clip and
member due to the offset between the bulb and web of the
member. The opposite end of the clip must be fastened to
the supporting structure in accordance with the approved
construction documents, prepared by a registered design
professional where required by statutes of the jurisdiction
in which the project is to be constructed.
5
4.2.7 Gypsum Board Attachment: Maximum /8-inchthick gypsum board must be installed and fastened to the
ceiling framing system (tees, main members and angle
moldings) in accordance with IBC Section 2508.
4.2.8 Lighting Fixtures: Lighting fixtures, when used,
must be independently supported by the structure.

5.6 For installations in Seismic Design Category C, D, E
or F, a quality assurance plan complying with ASCE
7, Section 11A, must be submitted to the code official.
5.7 Design calculations for loads outside the scope of this
report must be submitted to the code official at the
time of permit application. The calculations must be
prepared by a registered professional where required
by the statutes of the jurisdiction in which the project
is to be constructed.
5.8 The ceiling system is limited to ceilings not
considered accessible in accordance with Item 28
