Experimental Study on Fatigue Performance of Weathering Steel Plate after Corrosion
With the rapid development of transportation infrastructure,weathering steel has been widely used in bridges,highways and traffic signs due to its excellent resistance to atmospheric corrosion.In order to deeply explore the fatigue performance of weathering steel after corrosion environment and provide a more comprehensive evaluation of material application,this paper first expounds the corrosion mechanism of weathering steel plate,and then analyzes its fatigue crack propagation behavior and S-N curve through fatigue performance test.The results show that the weathering steel still maintains good fatigue performance after corrosion,and the protective rust layer effectively slows down the crack propagation,and its fatigue life is inversely proportional to the stress level.This study provides an important scientific basis for the application of weathering steel in traffic engineering,and provides a reference for its design and material selection.
