碩士 === 中原大學 === 土木工程研究所 === 93 === Early of the Twentith century, suspended bridge is the main type of the bridges such as Golden Gate bridge in 1937. With the computer development, cable-stayed bridges are on the upgrade after the world war Ⅱ. People have some demands about environment, economics, esthetics, and comfort, besides security. Because the cable-stayed bridge fit in with the conditions, it becomes one of the main types of the bridges. For cable-stayed bridges, the first course is the influence of the flutter, the buffeting, and the vortex shedding in cable-stayed bridge’s design and analysis. This article is composed with wind tunnel test of a cable-stayed bridge designed for the Taipei metropolitan area(include section model test and full model test) and the result of the formulas for wind velocity of flutter, buffeting, and vortex shedding. With the development and the progress of the bridge engineering technique, the span of the bridge is getting longer. The influence of the wind-force is an important factor that can't be ignored in long-span bridges design.
