鮎の瀬大橋の架設系における振動特性について(都市基盤デザイン工学科,工学部創設40周年記念号)

Abstract

There is no example examined in an experiment or analysis about the vibration characteristic of the structure under construction, and it has many unknown portions. In this paper, numerical analysis examined how the oscillation characteristic of a rigid frame bridge and cable stayed bridge which has different vibration characteristic would change in construction process. An object bridge is Ayunose Ohashi. Eigen-value analysis and earthquake response analysis were carried out for every construction step from the single system of a rigid frame bridge and cable stayed bridge until the completion system, and the vibration characteristic of each construction step was examined.
