How long does weathering steel last in a bridge?
As indicated earlier, weathering steel forms an adherent protective rust patina in suitable environments that inhibits further corrosion. According to SteelConstruction.info, the corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120-year design life with only nominal maintenance.See all results for this questionHow it Works: Engineering Bridges to Handle StressMar 17, 2017 · They constantly change, responding to different loads, weather patterns, and other types of stress in order to function. In some cases, much like a person undergoing a trauma, bridges must react to extremely stressful events like accidents, explosions, fires, Estimated Reading Time: 7 minsHow are steel bridges classified in the world?Steel bridges are classified according to the Type of traffic carried, type of main structural system and the position of carriageway relative to the main structural system. These classification of steel bridges are briefly discussed in this section. & Ad Free! EXPLORE VIP Membership Bridges are classified as:See all results for this question
