    Abstract: 斜張橋於更換纜索時猶如斷索的效應。本文將以三維薄壁結構的彈塑性大變形理論為基礎,在考量纜索中垂效應、橋塔與主梁的梁-柱效應、及整體結構的幾何大變形與材料非線性效應下,建立中跨徑斜張橋靜態抗風能力的分析模式。依研究結果顯示,斷索對中跨徑斜張橋來說,會改變初始風攻角的初始值,而且斷索位置不同,將導致極限風速隨之變化,但總體而言,對斷單一纜索的中跨徑斜張橋來說,其抗風能力仍處於合理範圍。
    This paper establishes an analytical model for statical wind resistance of middle-span cable-stayed bridges based on the elastic-plastic large displacement theory of 3-D thin-wall structures, and taking into consideration the cable sag effect, the beam-column effect on towers and beams, and the geometric large-deflection and material nonlinear effects on the entire structure. The results of the study show that, with respect to middle-span cable-stayed bridges, a broken cable changes the initial value of the initial angle of attack. Moreover, differences in the position of the broken cable lead to changes in limit wind velocity. But overall, with respect to a single broken cable on a middle-span cable-stayed bridge, the ability of wind resistance remains within a reasonable range.
