China Performance Of Weathering Steel Bridges

The performance of weathering steel depends on the proper formation of a dense layer of corrosion product,or patina,to protect the steel from further atmospheric corrosion.Initially,the corrosion rate of weathering steel is similar to that of plain carbon steel; however,wetting and drying cycles,or natural weathering,causes weathering steel to develop a dense oxide layer on the exposed surfaces.Cited by 125Publish Year 1984Author P Albrecht,A H NaeemiAssessment of Weathering Steel Bridge Performance in Iowa Feb 21,2013·Weathering steel is commonly used as a cost-effective alternative for bridge superstructures,as the costs and environmental impacts associated with the maintenance/replacement of paint coatings are theoretically eliminated.The performance of weathering steel depends on the proper formation of a surface patina,which consists of a dense layer of corrosion product used to protect theCited by 1Publish Year 2016Author Theodore Hopwood Ii,Sudhir Palle,Bobby W.Meade,Rick YounceCreated Date 11/25/2020 8:52:59 PMInspection and Maintenance of Weathering Steel BridgesApr 23,2015·Inspection and Maintenance of Weathering Steel Bridges.
