【摘要】 斜拉索是现代斜拉桥最重要的结构构件,成桥状态的结构内力和线型主要取决于合理成桥状态的索力。根据舟山桃夭门大桥的结构特点,选定并建立了鱼骨模型,在MIDAS/civil软件环境中确定了成桥状态索力,实践结果表明该方法可行。更多还原

【Abstract】 Stay cables are the most critical structural components in modern cable-stayed bridges.The structure internal force and linetype of Bridge-Completion state mostly depend on the reasonable cable tension.Based on the characteristics of the structure of Zhoushan-Taoyaomen bridge,the fishbone model is selected and builded.The cable tension of Bridge-Completion state is obtained in MIDAS software.The results indicate that the method is feasible.更多还原
