Rocking hinge bearing system for isolating structures from dynamic/seismic loads

摘要

A rocking hinge bearing system is provided. The rocking hinge bearing system comprises a first base plate, a second base plate, and a compressible member. A pintle mechanism aligns the first base plate, the second base plate and the compressible member and prevents relative horizontal movement between the first base plate, the second base plate and the compressible member. A tensioning mechanism inhibits axial separation of the first base plate relative to the second base plate and promotes returning the first base plate into its original position relative to the second base plate after rocking.
