摘要:
为了研究高强箍筋约束高强混凝土柱的抗震性能及轴压比限值，进行了10个高强箍筋约束高强混凝土柱在高轴压比下的低周反复水平加载试验。通过理论推导和对大量试验数据的回归分析，提出在不同抗震等级下高强箍筋约束高强混凝土柱的轴压比限值。研究结果表明：当体积配箍率大于1.2％时，高强复合箍筋约束高强混凝土柱在高轴压比（甚至轴压比超限）下，其位移延性系数均能满足大于等于3的抗震要求，即密配高强箍筋是保证高强混凝土框架柱在高轴压比下具有良好延性性能以及提高其轴压比限值的有效措施。
Abstract:
In order to study the seismic behavior and axial compression ratio limits of high-strength concrete (HSC) columns confined with high-strength stirrups, the lateral low cyclic loading tests of ten HSC columns confined with high-strength complex stirrups under high axial compression ratio were carried out. Through theoretical deduction and regression analysis of large numbers of test data, the axial compression ratio limits of HSC columns at different seismic levels were proposed. The study results show that the displacement ductility coefficient of columns under high axial compression ratio, even excessive axial compression ratios, will meet the seismic requirements of being equal or greater than 3, when the volume stirrup ratio is greater than 1.2%. So using highstrength stirrups closely spaced is an effective measure to ensure the HSC columns good ductility and enhance the axial compression ratio limits.
