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,分析了箍筋形式对延性的影响。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,3种箍筋形式相比,矩形加圆形复合箍和矩形加菱形复合箍试件的延性和耗能较好,井字形复合箍试件的延性和耗能较差。提高配箍特征值可改善试件的延性,增加试件的耗能能力,延缓试件的破坏。The main purpose of the paper is to study the hysteretie characteristics of high-strength concrete frame column under cyclic loading action, to discuss its ductility, to analyse the effect of shapes of hoop,6 roots of specimens have been tested, and the results show that, the ductilities of high-strength concrete specimens are lower than those of general concrete specimens; comparing three shapes of hoop,the ductilities and energy consumption properties of the test piece with the rectangle and circular compound hoop and the rectangle and rhomb compound hoop are better than these of the specimens with well-type compound hoop; increasing the reinforcement properties of hoop can improve the ductility of specimens, strengthen the capacity of energy consumption and delay the destruction of specimens.
