高层钢框架梁柱刚性连接节点的抗震设计

Seismic Design of Beam- column Connection in Highrise Steel Frame

综合比较了钢框架中改进的节点形式，采用带梁翼缘扩大的悬臂梁段高强螺栓拼接的梁柱节点作为设计方案。这种节点属于梁翼缘加强型节点，能够有效的将梁上的塑性铰外移，从而增强了结构的抗震性能。

After comprehensive comparison of improved beam - column joints in steel frames, beam - column connection with high- strength bolted flange- widened cantilever beam splicing is adopted during the design. This kind of connection is one type of flange - reinforced joints, which is capable of causing the plastic hinge in the beam away from the column flange effectively, so improving the seismic behavior of steel frames.
