劲性钢管混凝土拱桥的徐变效应分析

Creep Effects Analysis of Concrete Filled Steel Tube for Arch Bridge

以目前国内最大跨度的铁路钢管混凝土拱桥为例,对比拱肋中两部分混凝土发生徐变对结构的影响程度。在进行桥梁计算过程中,得出忽略拱肋内部的混凝土徐变对结构的影响偏于安全。

Taking the largest reinforced arch bridge in China as an example,a creep effect comparison of those two kinds of concrete is analyzed and some conclusions are concluded.In the calculation process,the concrete that the creep effect is omitted is safe for the structure.
