Patrick,
Since the total weight of the unit is less than 4001b, ASCE 7-16 Ch 13.1.4 does not require a seismic
analysis of the unit and no structural analysis of the framing is required.
CHAPTER 13
SEISMIC DESIGN REQUIREMENTS FOR NONSTRUCTURAL COMPONENTS
13.1 GENERAL
13.1.1 Scope. This chapter establishes minimum design criteria
for nonstructural components that are perrnanenlly attached to
structures and for their supports and attachments. Where the
weight of a nonstructural component is greater than or equal to
2514 of the effective seismic weight. W, of the structure as
defined in Section 12.7.2. the component shall be classified as a
mmbuilding structure and shall be designed in accordance with
Section 15.3.2.
13.1.2 Seismic Design Category. For the purposes of this
chapter, nonstructural components shall be assigned to the
same Seismic Design Category as the structure that they
occupy or to which they arc attached.
13.1.3 Component Importance Factor. All components shall
he &.,signed a component Importance Factor as indicated in this
section. The component Importance Factor, ly, shall he taken as
15 if any of the following conditions apply:
L The component is required to function for life -safety
purposes after an earthquake, including fire protection
sprinkler systems and egress stairways.
2. The component conveys, supports. or otherwise contains
toxic, highly toxic, or explosive substances where the
quantity of the material exceeds a threshold quantity
established by the Authority Having Jurisdiction and is
sufficient to pose a threat to the public if released.
3. The component is in or attached to a Risk Category IV
structure, and it is needed for continued operation of the
facility or its failure could impair the continued operation
of the facility.
4. The component conveys, supports, or otherwise contains
hazardous substances and is attached to a structure or
portion thereof classified by the Authority Having Juris-
diction as a ha7wdous occupancy.
All other components shall he assigned a component Impor-
tance Factor, Ir, equal to 1.0.
13.1.4 Exemptions, Tlic following nonstructural components
arc exempt from the requirements of this chapter:
L Furniture except storage cabinets, as noted in Table 13.5-1;
2. Temporary or movable equipment:
3. Architectural components in Seismic Design Category B.
other than parapets. provided that the component Impor-
tance Factor. 1, is equal to 1.0;
4. Mechanical and electrical components in Seismic Design
Category B;
5. Mechanical and electrical components in Seismic resign
Category C provided that either
a. The component Importance Factor. I is equal to 1.0
and die component is positively attached to the sttvo
lure: or
b. The component weighs 20 lb (89 N) or less or, in the
case of a distributed system, 5 lb/ft (73 N/m) or less.
6. Discrete mechanical and electrical components in Seismic
Design Categories D, E, or F that are positively attached to
the structure, provided that either
a. The component weighs 400 lb (1,779 N) or less, the
center of mass is located 4 ft (1.22 m) or less above the
adjacent Boor level. flexible connections are provided
between the component and associated ductwork. pip-
ing, and conduit and the component Importance Factor,
I is equal to 1.0; or
b. & component weighs 20lb (89 N) or lessor, in the case
of a distributed system, 5 lb/ft (73 N/m) or less: and.
7. Distribution systems in Seismic Design Categories D, E. or
F included in the exceptions for conduit cable tray. and
raceways in Section 13.6.5, duct systems in 13.6.6 and
piping and tubing systems in 13.6.7.3. Where in -line
components- such as valves, in -line suspended pumps. and
mixing boxes require independent support. they shall be
addressed as discrete components and shall he braced
considering the tributary contribution of die attached dis-
vibution system.
13.15 Premanuraclured Modular Mechanical and Electrical
Systems. Premanufacmred mechanical and electrical modules
6 ft (1.8 m) high and taller that are not otherwise prequalified in
accordance with Chapter 13 and that contain or support
mechanical and electrical components shall be designed in
accordance with the provisions for outbuilding structures
similar to buildings in Chapter 15. Nonstructural components
contained or supported within modular systems shall he designed
in accordance with Chapter 13.
13.1.6 Application of Nonstructural Component Require-
ments to Noubudding Structures, Nonbuilding structures
(including storage racks and tanks) that are supported by other
structures shall be designed in accordance with Chapter 15.
Where Section 15.3 requires that seismic forces be determined
in accordance with Chapter 13 and values for R,, are not provided
in Table 13.5-1 or 13.6-I, R,, shall be taken as equal to the value
of R listed in Chapter 15. The value of a„ shall be determined in
accordance with footnote a of Table 13.5-1 Lit 13.6-1.
13.1.7 Reference Documents. Where a reference document
provides a basis for the earthquake -resistant design of a
particular type of nonstructural component, that document is
permitted to be used. subject to the approval of the Authority
Having Jurisdiction and the following conditions:
Minimum Design Loads and Associated Criteria for Buildings and Other Structures
121
You shouldn't need anything from me to submit for permit.
Reference this email or give me a call if permitting requires structural information.

Ty,
Did you have an attachment?
Is there anything else I need from you to submit for permit?
Please send me an invoice for the current system.
I'll send the other projects in following emails this weekend or Monday.
Thank you,

Thanks for clarifying.
The current vibration dampening curbs are an excellent choice to reuse. Yes, the attachment will satisfy
the seismic requirements.

Ty,
Thanks for the quick reply...
This system is a 3 ton RTU
I will send the others separately.
The address for this location is
55 Pine St #304
Edmonds, WA 98020
No economizer on this residential unit.
I'd like to use the same mounting hardware... Can it be seismically connected?
Thank you ,
Pat

Patrick,
Thank you for the information.
I looked over the (E) and (N) cut sheets and the unit weights are indeed listed as the same.
I need the following information to start:
• Site address. Needed for seismic data and design.
• Which cooling capacity so I know what weight to use, 36, 42, or 48?
• Any additional weight to consider? Curb adaptors, new curbs, economizer, etc.
• How many units of each cooling capacity in total?

Ty,
It was nice talking with you last week. Sorry for the delay in getting back to you.
I have several RTU's needing replacement as we discussed.
They are like for like and I need the "stamp" of approval regarding weight and seismic info.
The first attachment is the old system and the new is the second.
Pics of existing equipment are also included.
Could you inform me of what is needed for seismic on the existing set up.
Let me know if you need anything else.
I'll try to send the other RTU's later today.
Thanks
Pat Brake
