摘　　要：通过13个框架柱试验,研究了高强混凝土框架长柱在低周反复荷载作用下的耗能性能,分析了轴压比、配箍特征值和配箍形式对框架柱耗能性能、延性的影响。试验结果表明:轴压比是决定高强混凝土试件延性和耗能的最主要因素,随着轴压比的增大,试件的延性和耗能降低;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;三种箍筋形式相比,矩形加圆形复合箍和矩形加菱形复合箍试件延性和耗能较好,井字型复合箍的试件延性和耗能较差。The capacity of energy consumption of high-strength concrete frame column under the action of cyclic loading is studied from the model test of 13 frame columns.The effect of axial compression ratio,reinforcement properties of hoop and shape of hoop on the ductility and energy consumption property of high-strength concrete specimens are discussed.The results show that the axial compression ratio is the most principal factor to determine the ductility and energy consumption property of high-strength concrete specimens.The ductility and energy consumption property will decrease with the axial compression ratio increasing;the reinforcement characteristic value of hoop increasing can improve the ductility of specimens,strengthen the capacity of energy consumption and delay the destruction of specimens.Comparing three types of stirrups,the compound hoop of rectangle with circular or compound hoop of rectangle with rhomb have better ductility and energy consumption properties than those of the specimens with compound hoop of decussation type.
