TAILIEUCHUNG - Weathering Steel

Weathering steel is NYSDOT’s first choice for steel multi-girder bridges under most conditions. This decision has been made in part because of the cost savings that can be realized due to decreased painting and maintenance requirements. However, recent studies have shown that this may not always be the case. This presentation will discuss some situations where bridges with weathering steel are underperforming and whether or not the situation can be rectified for future applications. | SESSION Weathering Steel Brian McMahon .

NYSDOT Region 4 Ontario Residency 585 396-4951 Synopsis Weathering steel is NYSDOT s first choice for steel multi-girder bridges under most conditions. This decision has been made in part because of the cost savings that can be realized due to decreased painting and maintenance requirements. However recent studies have shown that this may not always be the case. This presentation will discuss some situations where bridges with weathering steel are underperforming and whether or not the situation can be rectified for future applications. About the Presenters Brian McMahon is currently the Regional Design Engineer for NYSDOT in Rochester. During his 19 year career at NYSDOT he has also served as a Regional Structures Engineer and Engineer-In-Charge. He has a . degree in Civil Engineering from the University of Notre Dame and an MBA in Management from Syracuse University. Rich McFadden has been employed as an engineer for the New York State Department of Transportation for 21 years. He is currently on temporary assignment as the Assistant Resident Engineer for the Ontario Wayne County Transportation Maintenance Residency.

He has had varied engineering design experience throughout his career including major interstate interchanges to lift bridge rehabilitations and major bridge rehabilitations and replacements. Mr. McFadden has a . degree in Civil Engineering and Environmental Engineering from Clarkson University. So What Do You Do Is the sky falling because you are loosing section loss a lot quicker than advertised Are you going to get the full design life of the bridge of 70 years Where is the problem Is the section loss occurring at a .
