- Vibration reduction type railway station structure and spring-friction damper for the railway station structure

摘要

Even if the mass of the landing platform attenuates the tuning mass without adding added mass and the fluctuation of the structure or state of the landing platform occurs, it is possible to easily adjust the vibration characteristic to maintain the tuning mass damping action, thereby generating less vibration and noise, Railway history of the environment can be built at a low cost. The railroad history includes an upper structure provided with a rail on which a train travels, a lower structure supporting the load of the upper structure, a landing platform installed on the lower structure, and a platform installed between the lower structure and the platform, The vibration of the upper structure is suppressed by suppressing the vibration of the upper structure with respect to the lower structure by using a spring and friction to buffer impact force transmitted between the lower structure and the landing platform in accordance with the vertical vibration of the platform, And a spring-friction damper according to the present invention for causing the platform to cause a tuned mass attenuation action with respect to the lower structure.
