摘　　要：主要研究了高强混凝土框架长柱在低周反复荷载作用下的滞回特性,分析了配箍特征值对延性的影响。8根试件的试验结果表明,高强混凝土的延性比普通混凝土的延性差,提高配箍特征值可以改善其延性,增加其耗能能力。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 reinforcement properties of hoop, 8 roots of specimens have been tested, and the results show that, increasing the reinforcement properties of hoop can improve the ductility of specimens, strengthen the capacity of energy consumption and delay the destruction of specimens.
