中文摘要：

为研究高强度钢材钢结构的受力性能,了解国内外最新研究进展,促进该类新型绿色节能结构体系的更广泛应用,并为今后的相关研究提供参考和指导,对国内外高强度钢材钢结构的工程应用和最新的研究进展进行总结,特别是清华大学近期所做的一系列试验研究,包括高强度钢材的静力力学性能、韧性和循环荷载下的本构模型,构件截面的残余应力分布、受压钢柱的稳定性能和滞回性能、高强度钢材板件螺栓连接的延性和承载力,高强度钢材钢框架的抗震性能以及高强度钢材钢结构的相关有限元分析等内容。结果表明,高强度钢材钢结构在材料、构件和结构体系三个层面上都具有明显的优势,但现有的设计方法并不完全适用,需要发展新的设计理论和计算公式,以期更合理、安全地应用高强度钢材钢结构。

英文摘要：

High strength steel structures have many advantages and have been applied in many buildings and bridges in the world.To comprehend the mechanical performance and research progress of this new green structures and provide the guidance for further related studies,the engineering applications were introduced briefly,and the recent researches were reviewed,including the high strength steel static material performance and that under cyclic loadings,toughness,sectional residual stress,buckling and hysteretic behavior of high strength steel columns,the ductility and resistance of bolted connections with high strength steel slices,the seismic performance of high strength steel frames,and the finite element analysis（FEA）,especially with recent experimental studies conducted in Tsinghua University.All the results showed that high strength steel materials,members and structural systems had obvious superiority,but there were few reasonable design methods in current design specifications in the world.In order to make the application of high strength steel structures safe and more reasonable,new design theory and calculation formulae would be urgently needed.
