摘　　要：对考虑大气腐蚀影响的钢结构剩余抗震性能的现有研究进行综述,首先探讨了钢在大气环境下腐蚀程度随时间的变化规律,其次从材料、构件、结构体系3个层次梳理了腐蚀对钢结构抗震性能影响的研究现状,最后针对该领域当前研究的不足进行了详细评述。该领域下一步重点研究方向应包括腐蚀预测新方法、考虑蚀坑分布随机性的建模方法、焊缝腐蚀与焊缝超低周疲劳的交叉学科研究、适合腐蚀结构地震易损性分析的高效建模方法。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.
