摘    要:以经实桥实测温度场验证的有限元方法,以一座钢管混凝土哑铃形肋拱为基本分析对象,对其计算合拢温度、有效温度和平均温度内力进行了计算分析.研究结果表明,钢管混凝土哑铃形拱的计算合拢温度取值主要应考虑浇筑混凝土后28d的平均气温与哑铃形弦管管径;最高有效温度与当地最高气温相近,最低有效温度与当地最低日平均气温相近.论文还给出...

关 键 词:桥梁    钢管混凝土  哑铃形  温度

Abstract:Using finite element method verified by field temperature test of a bridge,the calculated closure temperature,maximum and minimum effective temperatures and temperature forces are studied by taking a CFST arch bridge with dumbbell shaped ribs as a case study.Research results show that for CFST arch with dumbbell shaped section,the average of the ambient temperature of the 28 d after the concrete filled into the tube and the diameter of the steel tube in the section are the two major factors which should be ...
Keywords:bridge  arch  concrete filled steel tube  dumbbell cross section  temperature
