In this section, we will review
anchorage and bracing requirements
for non-structural components.
We are going to talk about non-
structural component requirements in CBC
Chapter 16A and ASCE 7. 
One major subject of the nonstructural
components is anchorage and bracing.
Related inspection items can
be found in Inspection Manual
Section 2.5.
For the next 24 slides, we will
review following provisions:
Exceptions to bracing requirements,
Anchorage to concrete and masonry
Suspended ceiling provisions and
Pipe, duct and conduit provisions.
This picture shows a tall and slender
casework installed by the owner.
This casework was not
in the contract document.
When you encounter such item, you
should bring it to the attention
of the school district, the design
professional in charge and DSA.
We can quickly discover some
potential nonconforming conditions,
such as this casework may not
be properly anchored and braced.
It may interfere with
fire sprinkler coverage,
and the visibility of exit
signs and emergency strobe lights.
It could even block smoke
reaching a smoke detector.
CBC Section 1617A.1.18
replaces ASCE 7-16, Section 13.1.4.
With exemptions that certain
non-structural components are
exempt from the requirements of
seismic bracing and anchorage.
1.Furniture (except storage cabinets).
2.Temporary or moveable 
or mobile equipment.
There are a couple of exceptions
applicable to DSA projects.
A. Equipment shall be anchored
if it is permanently attached to the
building utility services, such as
electricity, gas, or water. For purposes
of this requirement, permanently
attached shall include all electrical
connections except plugs for
110 or 220 volt receptacles
having a flexible cable.
B. Moveable or mobile equipment,
which is heavier than 400 pounds,
or has a center of mass located 4'
or more above the adjacent floor
or roof level(that directly supports
such equipment) shall be restrained.
Mobile equipment shall be restrained
when not in use and is stored, unless
the equipment is stored in a storage
room that does not house hazardous
material or any facility system or
fixed equipment that can be affected
by mobile equipment lacking restraint.
The non-use 8 hour time limit which
triggers for anchorage of moveable,
mobile equipment has been repealed.
Third exemption of seismic bracing and
anchorage is: when the component is
positively attached to the structure
and flexible connections are provided
between the component and pipes, ducts,
and conduits and weight limits shown on
next slide are satisfied.
Weight limits: Component weighs less
than 400 lbs. or center of mass less
than 4' above supporting floor
or roof. Component weighs less than
20 pounds or in the case of a 
distributed system, 5 #/ft.
Now we are going to talk about
anchorage to concrete and masonry.
CBC Section 1617A.1.19 replaces
 ASCE 7-16, Section 13.4.2.3
For post-installed anchors and
specialty inserts to be used in concrete,
These anchors or inserts shall be
seismically prequalified using ACI 355.2
or 355.4 or ICC-ES Acceptance Criteria:
AC193, AC232, AC308 or AC446.
To be used in masonry,
these anchors or inserts shall be
seismically prequalified per ICC-ES,
AC01, AC58 or AC106.
Followings are limits on the use of
screw anchors: Use only at interior
dry locations. No reuse of screw
anchors or screw anchor holes.
Screw anchor are permitted
in building enclosures.
Power actuated fasteners(PAF)
shall not be used in concrete or steel
for sustained tension or as brace 
applications, unless approved for
seismic loading in accordance with
ICC-ES AC70. Shall not be
used in masonry unless approved for
seismic loading. Shall not be used
to anchor seismic bracing,
exterior cladding or 
curtain wall system.
Power actuated fasteners are
permitted to be used in concrete when
used for support of acoustical tile
ceilings, and distributed system
when the loads on the fastener
is not greater than 90 pounds.
It can be used in steel
when the loads on the fastener
is not greater than 250 pounds.
