Performance of Weathering Steel in TxDOT Bridges

Weathering steel bridges were soon built in Iowa and Ohio, and other states followed suit [1]. New Jersey was satisfied with the performance of its bridges [2]. In early 1965, the Michigan Highway Department (now Michigan Department of Transportation [MiDOT]) began the erection of four uncoated weathering steel bridges at the crossing of theSteel Bridge Fabrication - Transportation3.1.3 Weathering Steel Weathering steel has a certain metallurgical composition that permits the steel to form a protective coating and not require additional coatings to prevent corrosion. Material with this composition is appended with a W, e.g. Grade 50W indicates that F y = 50 ksi and it is a weathering steel.Steel Bridges - an overview | ScienceDirect TopicsWeiwei Lin, Teruhiko Yoda, in Bridge Engineering, 2017. 7.1 Introduction. Steel bridges are widely used around the world in different structural forms with different span length, such as highway bridges, railway bridges, and footbridges. The main advantages of structural steel over other construction materials are its strength, ductility, easy fabrication, and rapid construction.

For the case of weathering steel girders on ordinary structural steel bearings, there is no significant difference between the reactivity of the two metals and as the ordinary structural steel (of the bearings) is painted, there is no contact with an electrolyte. Hence bimetallic corrosion is unlikely to occur.Weathering steel in architectural applications.beams. they have supplied steel for bridges in the 150-ft to 200-ft-long range, with girder lengths of 60 ft to 80 ft. aStM a588 is the most common specifica-What is Corten Weathering Steel?You can weld weathering steel using the same flux combinations so that the tensile strength of the deposited weld metal (welding rod or wire) is consistent with the tensile strength of the base metal (weathering steel). Typical tensile strength of based metal (weathering steel) is 68-78 KSI. We would advise only welding A606-4 or A588 together.
