Seismic Snubber | Model HS-2

Seismic Snubber

Description

Model HS-2 Seismic Snubbers are designed for use in locations subject to earthquakes or other external forces which could displace resiliently supported equipment.

Snubbers, when anchored to the building structure and placed around vibration-isolated equipment, are intended to limit lateral motion by containing the supported equipment.

HS-2 Snubbers are designed to be used in pairs and will keep supported equipment contained when subjected to lateral forces from any direction. HS-2 Snubbers are not designed for use with high center-of-gravity supported equipment or where vertical forces must be considered.

Kinetics Model HS-2 Snubbers are heavy structural steel weldments designed to minimize equipment motion without failing. Resilient neoprene pads on the contact surface reduce shock loads by cushioning the impacts. Large diameter anchor bolt holes allow loads to be safely transferred to the building structure.

Application:

Building codes in many areas require building components to be capable of resisting forces created during a seismic event.

Equipment on resilient supports such as spring, neoprene or fiber glass vibration isolators can undergo large motions relative to the building during such an event.

By using properly spaced and designed resilient snubbers around the equipment, motion can be limited and equipment can remain in place.

Kinetics Model HS-2 Snubbers are rugged, heavy-duty products which have been designed to resist imposed forces from external sources, yet remain out of contact during normal operation so that vibration will not be transmitted to the building.

Specification:

(Equipment) (Equipment Bases) (Concrete Inertia Bases) (Structural Lateral Supports) shall be restrained against excessive movement during a seismic event by the use of resilient snubbers designed to resist (0.1) (0.2) (0.25) (0.5) (0.75) (1.0) (1.5) (2.0)g loads, or to meet current building codes. The steel members of the snubbers shall be designed to yield but not fail under design conditions. Calculations by a registered Professional Engineer or certified test reports shall be submitted which verify the capacity of each snubber.

Snubbers shall be welded steel and shall be attached to the building structure in a manner consistent with anticipated loads and shall meet current building codes.

Snubbers shall be placed around equipment as shown on drawings to limit lateral movement at each snubber to 1/8" (3 mm). A minimum of two snubbers shall be installed around each resiliently supported piece of equipment.

Snubbers shall include resilient pads to cushion any impact and shall be installed so as to be free of contact during equipment operation.

Snubbers shall be Model HS-2 by Kinetics Noise Control, Inc., Dublin, Ohio.
