摘　　要：对我国钢结构工程中超高强度钢材应用的可行性进行分析,从超高强度钢材的种类、化学成分及力学性能等方面进行介绍,分析超高强度钢材钢结构构件截面应力及初始缺陷对整体受压稳定性的影响。结果显示,与普通钢材相比,超高强度钢材轴心受压钢柱的整体稳定性更高,承载力更强,强度优势非常明显。在实际应用中,结合国内外多项建筑结构及超高强度钢材钢结构的优势,分析我国工程中对超高强度钢材钢结构的应用前景。This paper analyzes the feasibility of the application of ultra-high strength steel in steel structure engineering in Chi-na, and introduces the types, chemical composition and mechanical properties of ultra-high strength steel. The influence of sectionstress and initial imperfection on the compressive stability of ultra-high strength steel structure members is analyzed. The results showthat, compared with ordinary steel, ultra-high strength steel axial compression steel column overall stability is higher, bearing capacityis stronger, the strength advantage is very obvious. In practical application, based on the advantages of many building structures andultra-high strength steel structures at home and abroad, the application prospects of ultra-high strength steel structures in domesticengineering are analyzed.
