Gripple Seismic Restraint systems are specifi cally 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-specifi c 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.

Disclaimer:

Neither Michael J. Griffi n nor Gripple are the Structural or Professional Engineers of Record. The stability and adequacy of the structural elements, nonstructural components or seismic sway braces, hangers, brackets, bolting, anchorage and any other required attachments are the responsibility of the Structural or Professional Engineer of Record, or the seismic bracing design engineer for the Facility or Project. Any additional or supplementary members required to ensure the adequacy or stability of the structures the seismic sway bracing attaches to are not within the scope of this manual/document.

Gripple warrants that the Gripple Seismic Restraint systems will achieve the applicable design strengths published if installed in accordance with the guidelines contained in this manual. Gripple disclaims any and all other express or implied warranties of fi tness for any general or particular application. Anyone making use of this manual does so at their own risk, and assumes any and all liability resulting from such use.

1.4.1 Introduction / Transverse Brace Assembly

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.

1.4.2 Introduction / Longitudinal Brace Assembly

Longitudinal bracing acts to restrain the seismic forces in a plane parallel to the run of braced piping, conduit, ductwork or equipment, as shown above. The seismic forces that a longitudinal 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 longitudinal bracing is typically 80ft; 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 longitudinal bracing is typically 40ft; this brace spacing is dependent on pipe size, seismic forces, and brace components selected.

1.4.3 Introduction / 4-Way Bracing Assembly

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 specifi cations of the specifi c 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 2 dia, general conduit and ductwork) - 80ft for longitudinal bracing (piping larger than 2, general conduit and ductwork) - 30ft for transverse bracing (piping smaller than 2 dia) - 60ft for longitudinal bracing (piping smaller than 2 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 specifi c 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 fl exible joints between piping/conduit/ductwork and fl oor/ceiling mounted equipment.

Brace size and spacing should not vary considerably during a run to ensure uniform defl ection of the piping/conduit/ductwork along the run, and uniform loading of the individual braces during a seismic event.

Transverse bracing can be used as longitudinal bracing for an adjacent run (at 90 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 fl exible coupling due to differential movement of the pipe or conduit.

1.5 Introduction / Brace Spacing Guidelines (continued)

The minimum bracing required for runs longer than 5ft is a transverse brace at each end, and a longitudinal brace at one of these two positions. This bracing could be sourced using points 1 and 2 above.

1.5 Introduction / Brace Spacing Guidelines (continued)

Vertical runs must have both transverse and longitudinal bracing, or a 4-Way brace at each end of the vertical run. These bracing points must be located within 24 of the end of the vertical run, away from the change in direction.

4-way braces shall be provided at the top of all pipe ris-ers exceeding 3ft in length.

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. fl ex 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.
