| 摘 要： | 根据钢筋屈服点的不同,分别制作了一级钢筋、三级钢筋以及低屈服点钢筋的RC十字型节点;通过进行低周反复加载试验,得到了3种节点构件在水平荷载下的滞回曲线,分析比较了3种节点构件的耗能能力、延性、刚度退化等特征。试验结果表明:试件J-3在各级位移控制下第1循环的滞回环面积大于试件J-1、J-2;试件J-3的位移延性系数也远大于试件J-1、J-2;配置低屈服点钢筋的节点比配置一级钢、三级钢的节点耗能能力强,延性也有明显的提高。 |
| 关 键 词： | 十字型节点 低屈服点钢筋 低周反复加载试验 耗能能力 |

| Abstract: | According to different steel yield points,respectively,an HPB235-node,an HRB400-node and a low yield point steel RC cross-shaped node were produced.By conducting low cyclic loading tests,the hysteresis curves of three nodes at the horizontal loading were got.Authors analyzed and compared with the energy dissipation capacity,ductility,stiffness degradation characteristics of three nodes.The test results show that the hysteresis loop area of specimen J-3 at the first cycle under displacement control of all le... |
