Title: RESEARCH PAYS OFF: BRIDGE-TESTING TECHNIQUE RECEIVES HIGH RATING IN NEW YORK
Accession Number: 00667587
Record Type: Component
Availability: Find a library where document is available Abstract: Bridge engineers have been faced in recent years with an increasing need to reevaluate a growing number of older, sometimes deteriorated bridges. These bridges must often carry higher volumes and heavier traffic than they did when they were originally designed. In the evaluation of these bridges, attempts have been made to compensate for uncertainties by using conservative analysis techniques and idealized mathematical models to assess load-carrying capacity. This approach sometimes results in the removal, closing, or conservative load-limit posting of structures that may have excess capacity not accounted for in traditional analyses. Substantial benefits may be realized if appropriate candidate bridges can be evaluated through nondestructive load testing to assess their actual load-carrying capacity. In Steuben County, New York, engineers realized the potential of load testing, applied the methodology to a bridge, and were able to keep the bridge open without a load-limit posting. This article provides the details of the Steuben County bridge, a 1930s multigirder design with a concrete "jack arch" deck.
