Abstract

張弦桁橋は, ケーブルで主桁を下方から支持した自碇構造の橋である. 本論文では, 多数のストラットを有する張弦桁橋の基本的な力学特性を明らかにするとともに, 主桁剛性が全体系の静的特性, 動的特性などに及ぼす影響について検討した. また, 構造解析の妥当性を確認するために行った実橋における静的・動的載荷試験結果を示した. さらに, 主桁剛性が, 車両走行時および破壊時の挙動に及ぼす影響について検討を加えた.

This paper presents structural characteristics of a prestressed concrete deck bridge supported from below.<br>The prestressed concrete deck bridge supported from below consist of roadway deck, struts which support the deck, and subtending cables. The subtending forces balance the permanent loads as perfectly as possible.<br>A series of tests under static and dynamic loading are carried out on the Ayumi Bridge in Numazu City. The analytical model of the structure is confirmed by comparing the analytical results with the experimental results.<br>The dynamic responses of the bridge under the passage of moving vehicle are analysed for a parametric study. The non-linear analysis for ultimate loading was carried out using the fiber model program taking the material and geometrical nonlinearity into account.
