摘要
与普通结构钢相比,高性能钢具有更高的强度、延性、可焊性、断裂韧性以及耐火耐候性,至今已在国内外众多大型建筑和桥梁结构中得到应用。通过对国内外高性能钢的力学性能和相关工程应用的综述及与国外高性能钢材性能的对比,指出我国高性能钢发展和应用的瓶颈和亟待解决的问题。
Compared with common structural steel,high performance steels（ HPSs） generally have higher strength,ductility,better weldability, fracture toughness and fire-resistant and weathering properties. HPSs have been employed in many large-scaled building and bridge structures all over the world. In this study,the mechanical properties and engineering applications of both domestic and oversea HPSs were investigated,and items to hamper advancement and application of HPSs were pointed out through comparison between the state-of-art in China and overseas. Research needs to solve the aforementioned problems were also suggested.
