Residual Seismic Performance of Steel Structures Considering Influence of Atmospheric Corrosion:A Review
The aim of this paper is to summarize existing studies with regards to residual seismic performance of steel structures considering atmospheric corrosion.First,the variation laws of corrosion degree of mild steel with time in atmospheric environment is discussed.Then,state-of-the-art about the influence of atmospheric corrosion on seismic behavior of steel structures is reviewed from material,structural member,and structural system.Finally,a detailed review is provided on the limitations of currents studied in this field.A review of the current work indicates that further study should be focused on new methods of corrosion prediction,modeling method considering corrosion pits distribution randomness,interdisciplinary study on weld corrosion and weld ultra-low cycle fatigue(ULCF),and high-efficiency modeling method suitable for seismic fragility analysis of corroded steel structures.
