钢骨高强混凝土柱抗震性能敏感性因素的研究

Research on sensitive factors in behaviors of steel high-strength reinforced concrete columns

分析了轴压力系数和体积配箍率对钢骨高强混凝土柱抗震延性的影响,得出了满足一定位移延性要求、对应于不同体积配箍率的钢骨高强混凝土柱的轴压力系数限值,指出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。

The influences of axial compression ratio and stirrup ratio on seismic behaviors of SHRC columns are analyzed. The limited values of axial compression ratio of the columns are obtained, corresponding different stirrup ratios at a certain level of displacement ductility. And steel form is also an important factor. Axial compression ratio of the steel high-strength reinforced concrete columns with different steel form may be adjusted.
