OVERVIEW OF RESEARCH PROGRESS FOR HIGH STRENGTH STEEL STRUCTURES

High strength steel has been applied in many modern building and bridge steel structure constructions in recent years, due to their advantages in structural, architectural and economic benefits. Recent researches on mechanical performance of high strength steel structures in the level of both materials and members were comprehensively reviewed, including the static tension mechanical property, toughness, fracture and fatigue performance of high strength structural steel, the compression buckling and seismic behavior of high strength steel members, and the mechanical property of high strength steel connections. This literature review may provide a valuable information for both further relevant investigations and a proposal for design methods, and also promote the engineering application of high strength steel structures in China.
