摘　　要：采用有限元分析软件Ansys,对一焊接工字S形钢曲梁的稳定极限承载力进行分析,考虑几何和材料的非线性效应,对影响S形曲梁稳定极限承载力的拐点、圆心角、腹板高厚比和翼缘宽厚比等因素进行了较全面研究。This paper analyzed the ultimate bearing capacity of a welded I-section with S-shape curved beam with finite element software Ansys. Considered the geometric and material non-linearity , this article analyzed some factors which influence the ultimate bearing capacity of welded I-section with S-shape curved beam , such as point of knee bend,central angle,ratio of width-thickness of web and ratio of width-thickness of flange.

关 键 词：S形钢曲梁 极限承载力 拐点 圆心角
