摘要
1994年美国Northridge地震和 1995年日本阪神地震后 ,许多新型梁柱节点被提出 ,其中狗骨式节点是研究最多的一种节点形式。现结合实际工程对这种节点进行了试验研究 ,探讨了其在模拟地震荷载作用下的性能。试验结果表明 ,通过对节点附近梁上下翼缘进行合理的削弱可以增加节点的延性 ,同时对节点的刚度、强度影响很小 ,很好地改善了节点性能。
Since the 1994 Northridge earthquake and the 1995 Hanshen earthquake, a wide variety of different moment connections have been developed, the dog bone connection was a particularly popular moment connection. Based on the experimental investigation of dog bone connections of real structure, the performance of this kind of connection under simulated earthquake load is discussed. The experimental results show that, it can improve the performance of connection by trimming portions of the beam flange near the beam column connection with reasonable dimension, which can enhance the ductility and have little influence on the stiffness and the strength of connection. Then a design method of dog bone moment connections is put forward based on this experiment research and numerical analysis.
