| 摘 要： | 通过对７个常规框架柱试件在低周反复荷载下所进行的试验，重点研究了高轴压比下框 架柱的抗震性能以及轴压比的变化对框架柱滞回特性的影响。在对试件总体变形及塑性铰区域 局部变形量测结果统计分析和简化计算的基础上，研究了塑性铰区域的弯曲变形、剪切变形和节 点区钢筋的粘结滑移所产生的侧移在框架柱的总侧移中所占的比例及其规律。

| Abstract: | Seven 1/3 scale reinforced concrete columns were tested under high axial force and cyclic lateral load. The attention is focused on the seismic behavior of RC frame columns under high axial compression ratio and the effect of the change of axial compression ratio on their hysteretic characteristics. Based on the statistic of test results and a simplified analyses of the global and local deformation, the percentage of each of the deformation components due to flexure, shear within the plastic hinge zone and anchorage slip in the joint to the global deformation of the columns and their character were investigated. |
