ハイブリッド吊床版歩道橋の提案とその構造特性に関する基礎的研究(都市基盤デザイン工学科,工学部創設40周年記念号)

Abstract

Preliminary designs were made for the proposals for the 'stress-ribbon cable-stayed suspension' and the 'stress-ribbon suspension' bridges with open-grating deck plate for pedestrian use. The findings of this study revealed the followings: That the horizontal component of tensile force in the cable can be reduced up of the conventional concrete stress-ribbon bridges; the maximum deflection of the girder under asymmetrical live load can be well controlled by installing central clamps; the critical flutter speed is sufficiently high; and that vortex-induced oscillation does not occur.
