摘　　要：提出圆钢管混凝土柱-钢梁带软钢段节点,采用有限元软件ANSYS对其受力性能进行了非线性有限元分析,结果表明:圆钢管混凝土柱-钢梁带软钢段节点是一种理想的抗震耗能节点,并给出了软钢段起点至加强环边缘距离的合理取值范围。This paper presents a new connection model, Mild Steel Node, for the concrete filled circular steel column-steel beam system. The node is finite element analyzed by using ANASYS software. The results indicate that the concrete filled circular steel column-steel beam with mild steel nodes is an ideal seismic energy dissipation connection. The length of the mild steel con nections is also optimized based on the numerical analysis results.

关 键 词：钢管混凝土 软钢节点 非线性分析
