Abstract: In terms of constitutive relation of existed initial stress concreted??filled steel tubular, author analyses the influence of initial stress in concrete-filled steel tubular arch bridges. The results show initial stress reduces stability and bearing capacity of concrete-filled steel tubular arch bridge; the influence of initial is not equal to different load conditions. These conclusions offer reference for thorough study of the initial stress in large span concrete??filled steel tubular arch bridges in future.

Key words: concrete-filled steel tubular arch bridge, constitutive relation of initial stress concreted-filled steel tubular, Initial stress, stability and bearing capacity

摘要: 利用钢管砼的本构关系,分析钢管初始应力对钢管砼拱桥稳定承载力的影响程度.钢管初始应力的存在降低 了钢管砼拱桥稳定承载能力,不同荷载加载方式,钢管初始应力对钢管砼拱桥的稳定承载力影响程度不同.这为今 后深入研究大跨度钢管砼拱桥钢管初始应力问题提供了参考.
