摘要

本文應用有限元素法建立斜張橋結構非線性分析模式與相關電算程式，重點置於考慮溫度效應對斜張橋整體結構行為之影響。藉電子計算機模擬分析，探討溫度效應對橋面拱度、橋塔變位及桿件應力之影響，以期了解其對整個斜張橋結構行為之影響。本文取兩個斜張橋為例，首先針對全橋於常溫狀態與增溫狀態下，探討溫度效應對其結構行為之影響，並各別以雙、單懸臂工法，進行倒拆法逐段施工並同時考慮溫度效應對部分施工階段結構行為之影響。文中非線性效應考慮了樑柱效應及纜索中垂效應，且分析時僅針對非線性效應進行分析比較。預期研究結果將有助於提升對斜張橋結構行為有更進一步的了解。

The aim of this proposal concerns with the nonlinear analysis of cable-stayed bridges influenced by the thermal effect. A finite element computation procedure will be set up for the nonlinear analysis of such kind of structures including thermal effect. The structural behaviors of cable-stayed bridges influenced by thermal effect will be examined detailedly, such as the deflection of girders and towers, and the member forces induced by thermal effect.
