SEISMIC RETROFIT OF STEEL BRIDGES

The seismic resistance of New York State's steel bridges is improving as the Department of Transportation continues its rehabilitation process. Seismic retrofitting has been a part of the rehabilitation process, which involves the repair/replacement of deteriorated elements that in turn enhances the seismic resistance of the entire bridge structure. About 11,500 steel bridges require work on steel rocker or low sliding bearings. Maintenance-free elastomeric bearings are used as replacements. Another area of seismic retrofitting focuses on providing continuity to simply supported bridge structures. This retrofit improves the seismic resistance of the bridge, makes it a redundant structure, decreases the number of bearings, eliminates expansion joints in the deck, and reduces maintenance problems. This article provides details on the seismic retrofit of steel highway bridges in New York State.
