【 摘 要 】

In recent years, with the continuous rapidly development of the productivity and the production processing, the performance of steel has been continuously improved. High-strength performance steel has been used widely in long-span structures and tall buildings. The mechanical properties and the overall stability of axial compression members with Q460 high strength were summarized in the domestic and foreign in this paper. The differences between Q460 high strength and ordinary steel on the overall stability of axial compression members due to the differences in the mechanical properties of materials and the values and distribution of residual stress were analysed. It can provide reference for the study on the overall stability of axial compression members with high-strength performance.
