Weathering steel bridges constructed over or adjacent to other roadways could be subjected Assessment of Weathering Steel Bridge Performance in What causes steel bridges to deteriorate?What causes steel bridges to deteriorate?The steel bridges are generally very durable if properly maintained. The primary causes of metal bridge deterioration include the corrosion, fatigue, large deformations, and relaxation and drop off of high strength bolt.Steel Bridges - an overview ScienceDirect Topics What is fatigue in steel bridges?What is fatigue in steel bridges?Fatigue failure of steel bridges is another significant problem affecting the remaining service life of existing steel bridges. In general, fatigue can be defined as the weakening of steel materials or accumulation of damage at a localized region caused by cyclic loading or repeatedly applied loads.Steel Bridges - an overview ScienceDirect Topics

SESSION 2.4 Weathering Steel

WEATHERING STEEL Summary Weathering steel bridges should not be considered 100% maintenance free. Owners should be aware of the issues, especially with bridges in harsh environments. We will continue to use weathering steel, but will monitor performance more carefully. Moore Drive - coupon evaluation is ongoing.The performance of in-situ weathering steel in bridges Assessment of Weathering Steel Bridge Performance in Jul 07, 2015These use the time between echoes in the steel rather than the usual total transit time for the ultrasonic signal thereby giving only the steel thickness ignoring the thickness of the rust Conclusions A questionnaire circulated to weathering steel bridge owners has provided a database giving inventory and performance data on 141 weathering Assessment of Weathering Steel Bridge Performance in Uncoated Weathering Steel in Bridge StructuresTo better define the performance record of this material, the FHWA sponsored a Weathering Steel Forum in July of 1988 where knowledgeable speakers from across the nation were invited to present case histories and research data on the performance of this product in highway structures.
