Damping and suspension bridge construction method of the suspension bridge.

摘要

PROBLEM TO BE SOLVED: To make a width-direction end of a bridge girder unit connected to a main cable while maintaining rigidity and strength by a simple small-sized configuration, and to enable work such as transportation of machinery and materials, pavement and the like on the bridge girder unit.;SOLUTION: In a vibration control structure for a suspension bridge, a main girder is erected by suspending one width-direction end 3a of a bridge girder unit 3 and the other width-direction end 3b thereof from juxtaposed main cables 2. The vibration control structure for the suspension bridge includes a width end restraining device 4 which comprises an end fixing material 5 for vertically connecting the one and other width-direction ends 3a and 3b of the bridge girder unit 3 and each of the main cables 2, and an inclined fixing material 6 for obliquely connecting each of the main cable 2 and a position X, on the width-direction inside with respect to a lower end of the end fixing material 5, of the bridge girder unit 3.;COPYRIGHT: (C)2013,JPO&INPIT
