Mason Seismic Mounts

The Mason Seismic Mounts BR is a captive bridge bearing neoprene mount, capable of resisting Seismic, Mobile, Marine, and Wall Hung applications.

It is an ideal mount where only low deflections are required, but the application will see movement from seismic, wind or other forces.  The BR mount has bolt mounting hole patters for both I-Beam or steel installations, as well as concrete.

Captive Neoprene elements shall be arranged in opposition within a steel or ductile iron housing to provide positive mechanical restraint in all directions. Neoprene elements shall prevent metal to metal contact during normal operation. Bonded assemblies without mechanical interlocks are not acceptable.

Neoprene elements shall be of bridge bearing quality as tabulated. All mountings shall have minimum 1.0 horizontal G ratings and anchorage preapproval “OPA” numbers from the Office of Statewide Health Planning and Development (OSHPD) in the state of California prior to 2010, attesting to the maximum horizontal and vertical load ratings.

All mountings shall have bolts for rigid attachment to the equipment and adequate base bolting provision. Mountings shall have a minimum static deflection of 0.2” (5 mm). In seismic zones, submittals shall include calculations showing that the intersection of the horizontal and vertical seismic loads fall below the OSHPD approved curves.

Anchorages must be designed to meet the applicable building codes. All calculations must be signed by a professional engineer. Mountings shall be type BR as manufactured by Mason Industries, Inc.
