碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 104 === The motivation of this paper is that many domestic pedestrian bridges become a tourist attraction, because of its beautiful shape. The crowds of tourism often walk at the same side of the pedestrian bridges, as the result of that, there is a security issues of unbalanced load. The purpose of this research is to study the structural behavior of the cables of pedestrian suspension bridge under unbalanced loading. Another purpose of this paper is to reduce the risk of inclined suspension bridge under construction stage. The method of this study is, first, to build the bridge numerical model in order to analyze the deformation of the cables of the suspension bridge by commercial software, Secondly, to calculate amount of stretching and stress of the cables. Finally, the numerical result is discussed. The results of this study found that there occurs an additional stress in the main cable of the suspending bridge under construction stage.
