Weathering steel can be left unprotected in mild corrosive environments.The protective oxide layer developed on the surface of weathering steel is rougher than the surface of normal carbon steel,thus reduces fatigue strength.For this reason,EN 1993-1-9 reduces weathering steel plain member details in classes 160,140 and 125 to the next lower category.Cited by 6Publish Year 2012Author Ludv fatigue strength of weathering steel#237;k Kunz,Petr Luk fatigue strength of weathering steel#225;,Jan Klus fatigue strength of weathering steel#225;k(PDF) Fatigue Strength of Weathering SteelThe fatigue strength of unnotched test specimens from weathering structural steel WTSt 52-3 decreases as a result of exposure,which makes it necessary to

The phenomenal properties of weathering steel such as corrosion resistance,high strength,high-temperature resistance,and fatigue resistance make it suitable in outdoor decorations and buildings.According to the Institution of Civil Engineers,the global construction output is anticipated to reach USD 15.5 trillion by 2030.Guidance Note Use of weather resistant steel No.1details usually govern fatigue life.The corro-sion pits on a weathered surface are smaller than weld defects and therefore do not affect the fatigue life.Although Table 8.1 of EN 1993-1-9 (Ref 22) downrates the fatigue category for five unwelded details if the ele-ment is of weathering steel
Fatigue Life Weathering steel is progressively corroding,sometimes at an increasing rate if moisture is prevalent.Thus,there is a loss of steel mass and the fatigue strength is lessened.This means that a design using weathering steel may require thicker sections inImages
