    Abstract: 結構設計時,活載重位置變動會直接影響到斷面應力的分佈,因此可藉由影響線來確定活載重的臨界位置,進而得出斷面最大應力值,以做為斷面設計之依據。設計時主梁、橋塔及纜索彈性模數等皆會影響到各桿件應力及位移極值,所以如何將這些造成斜張橋影響線變化的控制因素做一分析和瞭解,將是重要的研究課題。本文除對纜索及主梁之勁度改變時對長跨徑斜張橋影響線造成之影響進行分析和探討外,對於增設輔助墩以及改採碳纖維索時對長跨徑斜張橋影響線造成之影響亦進行分析和探討。
    In the design of the cable-stayed bridges, the distribution of section forces will be affected by changing the position of live load, in hence, the critical position of live load can be determined by influence line. The limitations of stress and displacement in main girder, tower and cables will be controlled by some important parameters, such as, elastic modulus or stiffness of members, the installation of assistant pier and the material characteristics of carbon fiber cables. This study will discuss the characteristic of influence lines by considering these parameters.
