| 摘 要： | 在低周反复荷载作用下，进行７个１／３缩比钢筋混凝土框架柱试件的试验，重点研究在高轴压比下，常规钢筋混凝土框架柱的抗震性能，以及轴压比变化对框架柱滞回特性影响，研究结果表明，当设计轴压比达到０．９时，即使是具有良好的配筋构造，钢筋混凝土框架柱屈服后也将体现出较为明显的强度及刚度退化。

Antiseismic Performance Test of RC Framed Column with High Axial Compression Ratio |
| |
| Abstract: | By way of tests carrying out on 7 test specimens of framed column under subnormal frequency cyclic loading,a study is devoted to the antiseismic performance of framed column with high compresion ratio and also to the effect of axial compression ratio on the hysteresis characteristic of framed column.As shown by the results,with an axial compression ratio up to 0 9,the yielded RC framed column will reflect the degeneration of strength and stiffness even if there is good reinforced structure.Test and measurement are made on global deformation of testpiece and such local deformation components as bending deformation and shear deformation of plastic hinge zone and anchorage slip of steel bar at nodal zone.Based on statistical analysis and short cut calculation of these measuring results,a study is made on the lateral displacement due to these deformation components and on the their proportion in global lateral displacement of conventional framed column. |
