摘　　要：通过钢骨高强混凝土柱的承载力试验和在低周反复水平荷载作用下的试验研究，分析了长细比对柱受力性能的影响以及轴压比、配箍率及钢骨形式对柱抗震性能的影响。由试验得出钢骨高强混凝土长柱的承载能力随试件长细比的增大而降低，随混凝土强度等级的提高而提高，破坏的突然性随长细比的增大而俞益明显；另外，研究发现钢骨高强混凝土柱的抗震性能除对轴压力系数敏感外，钢骨形式也是一个重要的影响因素，对于钢骨形式不同的钢骨高强混凝土柱，可适当调整其轴压力系数限值，而配箍率的影响则并不显著。By the test on bearing capacity and level load of low cycle reverse of steel reinforced high-strength concrete columns, the influence on behaviors of the columns under different slenderness ratio and on anti-seismic behavior of the columns under different axial compression ratio, stirrup ratio and steel form, are analyzed, and that the~＇bearing capacity of the long columns reduces along with the slenderness ratio increasing and augments along with concrete strength increasing, and probability of suddenly destruct increases along with the column slenderness ratio augmenting, are obtained through the test. in addition, anti-seismic of the behavior columns is effected much not only by axial compression ratio, but also by steel form, is found in study, and axial compression ratio of the steel reinforced high-strength concrete columns with different steel form may be adjusted, however the influence of stirrup ratio is very little on anti-seismic behavior of columns.
