Abstract

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

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
