摘要
随着屈服强度的提高,高强度结构钢材的屈强比增大,断后伸长率减小,由于缺少相应规范条文,其在抗震设防地区的应用受到限制。从材料、构件和结构三个层面出发,总结了近年来国内外学者针对高强度钢材钢结构抗震性能的研究成果。重点包括:材料的静力拉伸力学性能、循环本构和极低周疲劳性能;柱、梁和连接节点的抗震性能;高强钢结构框架的抗震性能等内容。最后,对高强钢钢结构抗震性能的进一步研究工作进行了展望。
With the increase of yield strength,the yield-strength ratio of high strength structural steel increases,and the elongation ratio decreases.The application of high strength structural steel in seismic areas is limited due to the lack of relevant codes.This paper reviews research advances on seismic behavior of high strength steel structures in recent years at the level of material properties,the component members and the structures,and the corresponding findings are summarized.Highlights include:the static tensile mechanical properties,cyclic constitutive models and ultra-low cycle fatigue properties of materials,the seismic behavior of columns,beams and connections,and the seismic behavior of high strength steel frame structures.Finally,the prospect of further research on seismic behavior of high strength steel structures is presented.
