削弱深度对钢框架梁-柱刚性节点性能的影响

The Effect of Weakening Depth on Connection Prosperities of Beam-column Rigid joint

1994年美国的Northridge（北岭）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。本文通过非线性有限元方法，分析了八种削弱深度不同的狗骨式节点的承载性能和延性性能，得到了削弱深度的合理取值范围，对该类节点的推广应用具有指导意义。

After the Northridge earthquake in America in 1994 and Kobe earthquake in Japan in 1995, many new forms of beam-column connections were suggested, and dog-bone connection was researched best among them. In this paper, loading capability and ductility performance of dog-bone connection with eight different weakening depths were analyzed through nonlinear finite element method. Reasonable scale of weakening depth was reached and it has directive meaning for the spread application of this kind of connection.
