The life of CFT arch bridge can be divided into three stages: arch construction, beam construction and age, each of which relates to the other one. In the stage of service, displacement and interior force are changed with the effect of creep of core concrete. And the time-dependent deformation is calculated with the help of FEM software and special mechanical property in the process. The creep function of sealed concrete of ACI 209 and step-by-step method are used. The numerical result reveals that the creep...

The life of CFT arch bridge can be divided into three stages: arch construction, beam construction and age, each of which relates to the other one. In the stage of service, displacement and interior force are changed with the effect of creep of core concrete. And the time-dependent deformation is calculated with the help of FEM software and special mechanical property in the process. The creep function of sealed concrete of ACI 209 and step-by-step method are used. The numerical result reveals that the creep of CFT arch bridge is different from that of RC one, which lasts much longer than usual.

钢管混凝土拱桥的建造过程可以分为相互联系的三个阶段 :拱肋施工阶段、桥面系施工阶段和使用老化阶段 .计算中要考虑它们共同对结构的影响 .在使用老化阶段 ,拱桥在徐变会影响其变形和内部受力状态 .通过使用 ACI2 0 9密闭混凝土的徐变公式和逐步计算法 ,根据拱桥在徐变过程中的特点 ,利用有限元工具计算出拱桥的徐变结果 .从计算结果可以看出 ,钢管混凝土拱桥的徐变与普通有干燥的混凝土是不同的 ,表现在对数时间坐标上 ,其徐变变形即使在几十年后也不会趋于水平 .

Two aspects of properties are related to creep of concrete filled with steel tube(CFT) under axial load:creep function and computational method.Here the superposition method and creep function of sealed concrete of ACI209 R82 are used in the analysis to fit with the application in engineering.Elastic hypothesis and step by step method are used to compute the creep of core concrete under decreasing load.If there is confining pressure,the influence in radial and longitudinal direction is added to deduce the formula...

研究钢管混凝土在轴向载荷下的徐变特性涉及两方面 :徐变函数和计算方法。为适合工程应用 ,在徐变分析中采用“迭加法”和 ACI2 0 9- R82密闭混凝土徐变公式 ,就紧箍力的有无分别讨论钢管混凝土的时变特性。计算中采用弹性假设 ,通过离散时间的方法计算由于核心混凝土受载变化导致的徐变情况。在有紧箍力的情况下 ,考虑其在径向和轴向对钢管壁和核心混凝土的作用 ,利用弹性变形可迭加的性质得出徐变的表达式。
