VIBRATION ISOLATION STRUCTURE OF GERBER HIGH BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide the vibration isolation structure of Gerber type high bridge devising a solution plan suitable for reducing a vibration number by specifying the vibration number being a factor giving a discomfort feeling on the basis of vibration generation clarifying the vibration number giving stimulus on human sensation. SOLUTION: In the Gerber type high bridge composed of the unit high bridge comprising a frame structure between a plurality of spans and a beam girder part 1 installed between the unit high bridges, a solution plan is devised so as to reduce the vibration number giving a human being the discomfort feeling by constituting it so as to increase rigidity on the beam girder part 1 by making the beam girder part 1 an arch type.
