轴压比对高强混凝土框架柱滞回特性的研究

The Study of Axial Compression Ratio for High-Strength Concrete Frame Column the Hysteretic Characteristics

主要研究高强混凝土框架长柱在低周反复荷载作用下的滞回特性,分析轴压比对延性的影响.共进行了6根试件的试验,试验结果表明,高强混凝土的延性比普通混凝土的延性低,轴压比是决定高强混凝土试件延性和耗能的主要因素,随着轴压比的增大,试件的延性和耗能降低。

The main purpose of the paper is to study the hysteretic characteristics of high-strength concrete frame column under cyclic loading action, to discuss its ductility, to analyse the effect of axial compression ratio, 6 roots of specimens have been tested, and the results show that, the axial compression ratio is the most principal factor to determine. The ductility and energy consumption property will decrease with the axial compression ratio increasing.The results of paper offer edit of code.
