摘要： 通过大型通用软件ANSYS对不同温度、不同管径及不同径厚比的钢管砼拱桥主弦管的煨弯加工过程进行了 非线性稳定分析,找到了主弦管煨弯过程中发生局部鼓包现象的原因,得到主弦管煨弯失稳的判据,以此建立了以 截面弯矩为加载控制指标的煨弯控制方法

关键词: 钢管砼拱桥, 煨弯, 有限元, 非线性稳定分析

Abstract: The process of heat treated chord member for arch-bridge of CFST are analyzed by non-linear stability analysis through "ANSYS". With disparate temperature, diameter and diameter-thickness ratio, the discriminant for buckling moment is found out. From this, the method of heat treated chord member for arch-bridge of CFST is suggested

Key words: arch-bridge of CFST, heat treatment, FEA, non-linear stability analysis
