摘　　要：国内某高铁火车站地下地铁站结构,采用钢管混凝土柱和普遍钢筋混凝土梁结构形式。节点拟采用传统的焊接节点和长圆孔变型性高强螺栓节点两种方案。文章通过有限元软件对这两种节点方案在地震作用下的延性变形能力、滞回性能、耗能能力、塑性转角等进行分析与对比。有限元分析结果表明,螺栓节点拥有较好的延性性能和抗震性能。A domestic high iron railway station underground subway station structure adopts concrete filled steel tube column and common reinforced concrete beam structure form. Node have two schemes： the traditional welded joint and high strength bolt connections with slotted holes. The ductile deformation ability, hysteretic property, energy dissipation, plastic rotation capacity of these two kinds of node scheme under the effects of earthquake forces are ana- lyzed and compared base on the finite element analysis. Finite element analysis results show that the bolt node have good ductility performance and seismic performance.
