VIBRATION CONTROL OF POSTS ON BRIDGE USING TUNED MASS DAMPERS

摘要

The present invention relates to a vibration damping structure of a bridge, and can reduce the horizontal and twisting direction vibrations as well as the vertical direction vibration caused by the long span in a pedestrian overpass, thereby improving the psychological anxiety of pedestrians and improving the durability of the facility. This is to improve it.;The present invention for realizing this, the guide rod 20 configured in the vertical direction on both sides of the box-shaped housing 10, and the main mass body 30 which is guided by the guide rod 20 and configured to flow up and down; , A sub-mass body 40 supported by the plurality of elastic springs 41 in the space part 33 formed at the center of the main mass body 30, and a support spring supporting the main mass body 30 with an elastic force from the bottom. And an oil damper 50 into which the lower ends of both legs 32 of the main mass 30 are inserted.;Bridge, Vibration, Overpass, Tuned Mass Attenuation, Vertical, Horizontal, Warp
