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 increasingly used in modern steel structures, such as high-rise buildings, long-span bridges, and power towers, but component stability issues have become major constraints on their use. The latest achievements made by domestic and foreign scholars on the research of the stability of high strength steel components are introduced in detail, including the mechanical properties and residual stress test of high tensile strength steel at room temperature under static load, as well as the local stability, overall stability, local stability and overall stability Relevance. At the same time, it points out the problems existing in the existing research and provides reference for the design of high strength steel structure and further research.
