| 摘 要： | 在四榀高强混凝土框架节点及两榀钢纤维高强混凝土框架节点缩尺模型抗震性能试验的基础上．对高强混凝土框架节点和钢纤维高强混凝土框架节点梁端抗弯承载力、梁端抗剪承载力、位移延性及耗能性能进行了分析．结果表明，钢纤维高强混凝土材料能明显提高节点的初裂值及抗剪承载力，有较好的延性。从而可以在核心区少配箍筋．甚至不配箍筋．这样既保证了抗震性能要求．又解决了框架节点区钢筋密布而带来的施工困难．有良好的经济效益。 |
| 关 键 词： | 钢纤维高强混凝土 框架节点 塑性铰 延性 |

| Abstract: | Through the experimental research of four high strength reinforced concrete frame joints and two steel fiber high strength reinforced concrete frame joints under low cyclic loads,it was found that the steel fiber concrete frame joint had better ductility, higher cracking and shear capacity of joints. The stirrup of the core of the steel fiber concrete frame joint had fewer stirrups or even no stirrups. That can deal with the construction difficulties as well as meet the requirements of engineering seismic resistant practice and thus bring good economic benefits. |
| Keywords: | high strength reinforced concrete frame joint plastic hinge ductility |
