摘　　要： 高强度钢材被越来越多地应用于现代钢结构,例如高层建筑、大跨度桥梁和输电塔中,但构件的稳定问题成为限制其应用的主要因素。详细介绍了国内外学者在高强钢构件稳定性能研究方面取得的最新成果,包括高强钢材料常温静载一次拉伸的力学性能、残余应力测试,以及构件的局部稳定、整体稳定、局部和整体稳定的相关性。同时,指出已有研究存在的问题,为高强钢结构设计及进一步的研究提供参考。 High strength steels are becoming more and more widely used in modern steel structures,such as high rise buildings,long-span bridges and transmission towers.But this change is hindered mainly by the buckling failure of high strength steel members.In this paper,recent advances in research on stability behavior of high strength steel members at home and abroad are reported in detail.These research achievements include the mechanical properties of high strength steel materials under the conditions of static loading at room temperature and stretching along the longitudinal direction only one time,measurements of residual stresses,as well as local buckling,overall buckling and local-overall interactive buckling behavior of columns,beams and beam-columns fabricated from high strength steels.In addition,the problems that exist in the research are also pointed out.It will provide reference for design and further research of high strength steel structures.
