Weathering steel has been a primary construction material for bridges in the
United States. Notches caused by corrosion are observed on the flange of steel
I-beams. These notches reduce the cross section area of the structure and are
threats to bridge safety. A606-04 Type 4 cold rolled weathering steel samples
were studied in this thesis to understand the effect of notches that caused by
corrosion. Weathering steel samples were in the shape of plates, which simulated
flange of I-beams. The plate samples were notched across their surfaces by
applying electrical current through an electrochemical circuit composed of an
anode, a cathode and electrolyte. Sixteen samples were notched and cut into
appropriate shape for fatigue testing. S-N (Stress-Number of cycles to failure)
diagram established from fatigue data indicated that the fatigue strength
decreased below AASHTO category B. Weibull analysis was also performed to
understand the reliability distribution. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection
