Field verify that any armover with a total horizontal length of 24" or longer is provided with a
hanger, per NFPA-13, 2013, section 9.2.3.5.1.
Verify that the pressure at the base of the riser does not exceed 100 psi, or verify that the
maximum length of unsupported armover supplying a sprinkler below the ceiling does not
exceed 12" per NFPA-13, 2013, section 9.2.3.5.2, and that such a hanger resists upward
movement of the piping, per section 9.2.3.5.2.2
In the event that the t-bar ceilings are not rigidly braced per ASME E580, the sprinklers to be
installed in the suspended panels will require either a 2" clearance around the penetration
through the panel, or the use of a flexible drop fitting, per ASCE7-10, section 13.5.6.2.1
through 15.6.3, which is attached. However, gypsum board ceilings are assumed to be rigidly
braced. All the above conditions can be field verified.
As the portions of the system revision cannot be isolated from the existing, the system should
not be subjected to a hydrostatic test at greater than normal system pressure. See NFPA 13,
section 25.2.1.6.

CHAPTER 13 SEISMIC DESIGN REQUIREMENTS FOR NONSTRUCTURAL COMPONENTS
13.5 ARCHITECTURAL COMPONENTS
13.5.1 General
Architectural components, and their supports and
attachments, shall satisfy the requirements of this
section. Appropriate coefficients shall be selected
from Table 13.5-1.
EXCEPTION: Components supported by chains
or otherwise suspended from the structure are not
required to satisfy the seismic force and relative
displacement requirements provided they meet all of
the following criteria:
The design load for such items shall be equal to
1.4 times the operating weight acting down with a
simultaneous horizontal load equal to 1.4 times the
operating weight. The horizontal load shall be
applied in the direction that results in the most
critical loading for design.
Seismic interaction effects shall be considered in
accordance with Section 13.2.3.
The connection to the structure shall allow 'a 3600
range of motion in the horizontal plane.
13.5.2 Forces and Displacements
All architectural components, and their supports
and attachments, shall be designed for the seismic
forces defined in Section 13.3.1.
Architectural components that could pose a
life-safety hazard shall be designed to accommodate
the seismic relative displacement requirements of
Section 13.3.2. Architectural components shall be
designed considering vertical deflection due to joint
rotation of cantilever structural members.
13.5.3 Exterior Nonstructural Wall Elements
and Connections
Exterior nonstructural wall panels or elements
that are attached to or enclose the structure shall be
designed to accommodate the seismic relative dis-
placements defined in Section 13.3.2 and movements
due to temperature changes. Such elements shall be
supported by means of positive and direct structural
supports or by mechanical connections and fasteners
in accordance with the following requirements:
Connections and panel joints shall allow for the
story drift caused by relative seismic displacements
(Dr) determined in Section 13.3.2, or 0.5 in. (13
mm), whichever, is greatest.
Connections to permit movement in the plane of
the panel for story drift shall be sliding connections
using slotted or oversize holes, connections that
permit movement by bending of steel, or other
connections that provide equivalent sliding or
ductile capacity.
The connecting member itself shall have sufficient
ductility and rotation capacity to preclude fracture
of the concrete or brittle failures at or near welds.
All fasteners in the connecting system such as
bolts, inserts, welds, and dowels and the body of
the connectors shall be designed for the force (Fr)
determined by Section 13.3.1 with values of R and
a, taken from Table 13.5-1. applied at the center of
mass of the panel.
Where anchorage is achieved using flat straps
embedded in concrete or masonry, such straps shall
be attached to or hooked around reinforcing steel
or otherwise terminated so as to effectively transfer
forces to the reinforcing steel or to assure that
pullout of anchorage is not the initial failure
mechanism.
13.5.4 Glass
Glass in glazed curtain walls and storefronts
shall be designed and installed in accordance with
Section 13.5.9.
13.5.5 Out-of-Plane Bending
Transverse or out-of-plane bending or deforma-
tion of a component or system that is subjected to
forces as determined in Section 13.5.2 shall not exceed
the deflection capability of the component or system.
13.5.6 Suspended Ceilings
Suspended ccihiIgs shall be in accordance,with
this section.
EXCEPTIONS:
I. Suspended ceilings with areas less than or equal to
144 ft' (13.4 m2) that are surrounded by walls or
soffits that are laterally braced to the structure
above are exempt from the requirements of this
section.
2. Suspended ceilings constructed of screw- or
nail-attached gypsum board on one level that are
surrounded by and connected to walls or soffits
that are laterally braced to the structure above are
exempt from the requirements of this section.
13.5.6.1 Seismic Forces
The weight of the ceiling, W,,, shall include the
ceiling grid; ceiling tiles or panels; light fixtures if
attached to, clipped to, or laterally supported by the
ceiling grid; and other components that are laterally
supported by the ceiling. W shall be taken as not less
than 4 psf (192 NIm2).

13.5.7 Access Floors
13.5,7.1 General
The weight of the access floor, W,,, shall include
the weight of the floor system, 100 percent of the
weight of all equipment fastened to the floor, and 25
percent of the weight of all equipment supported by
but not fastened to the floor. The seismic force, F,
shall be transmitted from the top surface of the access
floor to the supporting Structure.
Overturning effects of equipment fastened to the
access floor panels also shall be considered. The
ability of "slip on" heads for pedestals shall be
evaluated for suitability to transfer overturning effects
of equipment.
Where checking individual pedestals for overturn-
ing effects, the maximum concurrent axial load shall
not exceed the portion of W, assigned to the pedestal
under consideration.
13.5.7.2 Special Access Floors
Access floors shall be considered to be "special
access floors" if they are designed to comply with the
following considerations:
Connections transmitting seismic loads consist of
mechanical fasteners, anchors satisfying the
requirements of Appendix D of ACI 3.18, welding,
or bearing. Design load capacities comply with
recognized design codes and/or certified test
results.
Seismic loads are not transmitted by friction,
power actuated fasteners, adhesives, or by friction
produced solely by the effects of gravity.
The design analysis of the bracing system includes
the destabilizing effects of individual members
buckling in compression.
Bracing and pedestals are of structural or mechani-
cal shapes produced to ASTM specifications that
specify minimum mechanical properties. Electrical
tubing shall not be used.
Floor stringers that are designed to carry axial
seismic loads and that are mechanically fastened to
the supporting pedestals are used.

Partitions that are tied to the ceiling and all
partitions greater than 6 ft (1.8 m) in height shall be
