1.1 Introduction / Scope
Gripple Seismic Restraint systems are specifically designed and engineered to brace and secure nonstructural
equipment and components within a building or structure to minimize earthquake damage to suspended
components.
Gripple Seismic Restraint systems are ideal for use on nonstructural components and equipment requiring
seismic design, such as in essential facilities that are required for emergency operations in the aftermath of an
earthquake.
Detailed in this manual are bracing guidelines for a variety of nonstructural components, equipment, and
systems. Actual restraint requirements for some sites may vary from these guidelines, and these site-specific
restraint installations are not limited to the guidelines detailed here. However, ensure that any deviations from
the guidelines within this manual are pre-approved by the seismic engineer of record for the particular site.
It is the responsibility of the reader and structural engineer for the project/site to ensure that the existing
structure is capable of withstanding the full loads that may be induced by the braced equipment or Seismic
attachments.
The services of a seismic bracing engineer or a professional/structural engineer is required to determine the
seismic demand forces, required bracing, spacing, and anchorage of the bracing in accordance with the
applicable building code design provisions and conditions for the project.
Please note that this manual does not replace code-required industry standard practices. Gripple Seismic
Restraint systems, designed as per the guidelines outlined in this manual, do not guarantee adequacy of the
installation, and it is the responsibility of the reader and structural engineer for the site/project to ensure the
adequacy of the design and placement of the Seismic bracing kits and their installation to be in compliance
with the applicable codes.

Transverse bracing acts to restrain the seismic forces in a plane perpendicular to the run of braced piping, conduit,
ductwork or equipment, as shown above. The seismic forces that a transverse brace resists are illustrated by Fh.
A vertical force can be generated during a seismic event and as such, rod stiffeners may be required to help prevent the
hanger rod from buckling under this upwards force.
Ductile Braced Components:
For piping, conduit, and equipment connections manufactured from ductile materials, the maximum allowable brace
spacing for transverse bracing is typically 40ft; this brace spacing is dependent on pipe size, seismic forces, and brace
components selected.
Non-ductile Braced Components:
For piping, conduit, and equipment connections manufactured from non-ductile materials, the maximum allowable brace
spacing for transverse bracing is typically 20ft; this brace spacing is dependent on pipe size, seismic forces, and brace
components selected.
Refer to Section 1.5 for spacing guidelines.

4-Way bracing acts to restrain the seismic forces of the run of braced piping, conduit, ductwork or equipment, in both the
transverse and longitudinal directions, as shown above. The seismic forces that a 4-Way brace resists are illustrated by
Fh. A vertical force can be generated during a seismic event and as such, rod stiffeners may be required to help prevent
the hanger rod from buckling under this upwards force.
Ductile Braced Components:
For piping, conduit, and equipment connections manufactured from ductile materials, the maximum allowable brace
spacing for 4-Way bracing is typically limited to 80ft, so long as transverse bracing is used in addition, every 40ft; this
brace spacing is dependent on pipe size, seismic forces, and brace components selected.
Non-ductile Braced Components:
For piping, conduit, and equipment connections manufactured from non-ductile materials, the maximum allowable brace
spacing for 4-Way bracing is typically limited to 40ft, so long as transverse bracing is used in addition, every 20ft; this
brace spacing is dependent on pipe size, seismic forces, and brace components selected.

1.5 Introduction / Brace Spacing Guidelines
Gripple Seismic Bracing must be installed on the vertical support system comprised of threaded rod (all-thread rod) hanger
suspensions, or directly to a suspended individual equipment component.
Seismic bracing shall be designed in accordance with:
- the applicable building code or local city/county code requirements for seismic design.
- the engineering drawings and specifications of the specific project requirements.
Component hanger spacing will typically be less than the required seismic spacing.
Typical maximum allowable brace spacing limits
The maximum allowable brace spacing for piping/conduit/ductwork constructed of ductile materials (e.g. steel, copper, aluminum) are typically:
- 40ft for transverse bracing (piping larger than 2½“ dia, general conduit and ductwork)
- 80ft for longitudinal bracing (piping larger than 2½“, general conduit and ductwork)
- 30ft for transverse bracing (piping smaller than 2½“ dia)
- 60ft for longitudinal bracing (piping smaller than 2½“ dia)
The maximum allowable brace spacing limits for piping/conduit/ductwork constructed of non-ductile materials (e.g. cast iron, plastic)
are:
- 20ft for transverse bracing
- 40ft for longitudinal bracing
The brace spacing could be considerably less than this for a specific run, depending on the seismic demand loads, the size and
load capacity of the cable brace system used, and the strength of the structural members/components and structural anchors
which resist the resulting seismic brace forces.
Reduced spacing may also be required to prevent:
- collisions between the piping/conduit/ductwork/equipment and other non-structural components.
- rupture/shearing/slippage of flexible joints between piping/conduit/ductwork and floor/ceiling mounted equipment.
Brace size and spacing should not vary considerably during a run to ensure uniform deflection of the piping/conduit/ductwork
along the run, and uniform loading of the individual braces during a seismic event.

Transverse

•
Transverse bracing can be used as longitudinal bracing for an
adjacent run (at 90º changes of direction) where the brace is
located less than 24” from the change in direction.
•
Longitudinal/Transverse sway bracing shall also be required
within 24” of every flexible coupling due to differential movement
of the pipe or conduit.

Each unit of equipment connected to a run of piping/conduit/ductwork should be individually and independently braced. If
rigidly connected to the piping/conduit/ductwork, then the equipment bracing shall also be designed for the tributary piping/
conduit/ductwork seismic forces. If the piping/conduit/ductwork is not rigidly connected, i.e. flex joints, then the equipment
bracing cannot be used to brace the adjacent piping/conduit/ductwork and shall be independently braced.
•
Suspended rectangular units of equipment shall be provided with a minimum of one sway brace at each corner (4 total
braces). See Section 5 for details.
