钢筋混凝土框架柱轴压比限值问题研究

INVESTIGATION ON LIMIT VALUES OF AXIAL COMPRESSIVE STRESS RATIO FOR RC FRAME COLUMNS

针对目前高层钢筋混凝土结构抗震设计中遇到的突出问题之一——框架柱轴压比超限现象,结合以往试验现象分析和对规范背景资料的研究,对框架柱轴压比限值的研究进行了综述与分析,并对进一步的研究工作提出了一些新的建议。

This paper engages in the problem of exceeding the limit value of axial compressive stress ratio for RC frame columns, which is usually met in the earthquake-resistant designing of RC high-rising building. With the analysis of experiments done in the past and the background of the code, the fundamental principle on specifying limit values of axial compressive stress ratio is discussed. Finally, some new ideas are recommended.
