中文摘要	超高强度钢材已在国外多个钢结构工程中得到应用,国外学者也针对此类钢材开展了有关构件初始缺陷、整体稳定和局部稳定性能、钢材的疲劳和断裂性能等方面的研究,而国内这方面研究则刚刚起步。本文主要介绍新型超高强度钢材钢结构在国内外实际工程中的应用,总结和分析超高强度钢材钢结构稳定、疲劳、断裂等方面的受力性能,并与我国钢结构设计规范中对于普通强度钢材钢结构的相关规定进行对比,揭示超高强度钢材钢结构受力性能的特点和优势,为今后我国开展此类结构的研究工作提供参考,促进新型超高强度钢材钢结构在我国的工程应用。; Ultra-high strength steels with nominal yield strength more than 460MPa have begun to be applied in many steel structures, some research on which, including initial imperfections, overall and local buckling, fatigue, fracture and so on, have been conducted abroad, while in China the related research just begins. In this paper, the engineering application of ultra-high strength steels in china and other countries has been reviewed, as well as the mechanical behavior on stability, fatigue and fracture for ultra-high strength steel members have been summarized and analyzed, which are also compared with corresponding regulations in Chinese steel structure design code for ordinary strength steels. Finally, the characteristics and advantages of ultra-high strength steel structure have been proposed, which can give reference for the following research, and would be helpful for the application of the ultra-high strength steel structures in our country.
