Seismic Snubbers

All directional seismic snubbers shall consist of interlocking steel members restrained by shock absorbent rubber materials compounded to bridge bearing specifications. Elastomeric materials shall be replaceable and a minimum of 3/4” (19mm) thick. Rated loadings shall not exceed 1000 psi (.7kg/mm2). Snubbers shall be manufactured with an air gap between hard and resilient material of not less than 1/8” (3mm) nor more that 1/4” (6mm). Snubbers shall be installed with factory set clearances. The capacity of the seismic snubber at 3/8” (9mm) deflection shall be equal or greater than the load assigned to the mounting grouping controlled by the snubber multiplied by the applicable “G” force. Submittals shall include the load deflection curves up to 1/2” (13mm) deflection in the x, y and z planes. Snubbers shall have an anchorage preapproval “OPA” number from OSHPD in the state of California verifying the maximum certified horizontal and vertical load ratings. Snubbers shall be type Z-1011 as manufactured by Mason Industries, Inc.
