Vibration Control Device TMD [Example] Measures for Building Floor Vibration Due to Shinkansen

We implemented measures by innovating points such as the diversification of TMD units! We were able to achieve sufficient effects over a wide frequency range.

We will introduce a case study on building floor vibration countermeasures due to the Shinkansen. There is a Shinkansen elevated track right next to the building, and floor vibrations occurred during the passage of trains. Different trends were observed depending on the passage speed and the location of occurrence, but by installing a damping device in the ceiling and implementing appropriate adjustments, improvements were achieved. [Case Summary] ■ Key points of the countermeasures: Creativity is necessary to address the variation in generated frequencies. ■ Investigation details: Confirmation of current vibrations and understanding of the vibration characteristics of the building. ■ Results and summary of the countermeasures: Through suitable adjustments on-site, sufficient effects were obtained over a wide frequency range. *For more details, please refer to the PDF document or feel free to contact us.
