APPLICATION OF ISOLATION BEARINGS TO BRIDGES IN LOW TO MODERATE SEISMIC AREAS

This paper describes experiences on the use of various types of passive isolation bearings for seismic retrofit of existing bridges and construction of new bridges. The cost of these bearings is often offset by the savings in substructure retrofit or construction costs. Past experience has shown that a key element in reducing the unit cost of isolation bearings is a generic design allowing use of various isolation bearing types that either reduce seismic forces to a level below the as-built capacity of an existing bridge or lower design seismic forces or a new structure.
