本文从框架柱大小偏心受压破坏角度出发，阐述了规定轴压比限值对保证压弯构件延性的必要性，并根据国内外学者的研究成果，就普通混凝土柱、高强混凝土柱、劲性混凝土柱各自轴压比的定义式及其限值进行了分析与比较，从概念上说明了以上各限值的大小关系。介绍了劲性骨架高强混凝土压弯柱的低周伪静力试验研究结果，结合试验结果提出了其轴压比和轴力比限值的建议 This paper expounds the necessity of specifying the axial compression ratio limit to ensure the ductility of the compression-bending components from the perspective of the collapse of the size of the frame column eccentric compression, and according to the research results of scholars at home and abroad, on ordinary concrete columns, high-strength concrete columns, and stiffness The definitions and limits of the axial compression ratios of concrete columns were analyzed and compared, and the relationship between the above limits was conceptually illustrated. The low-period pseudo-static test results of stiffened high-strength concrete columns are introduced. The results of the axial compression ratio and axial force ratio limit are put forward based on the experimental results.
