Vertical Nori Vibration Control in Buildings
In recent years, there has been an increase in the number of complexes and tenant buildings that house facilities for various purposes. In particular, the vertical groove vibration of dances and live performances in sports facilities, studios, halls, etc. is often a problem because the vibration is so large that it travels through the building and adversely affects other stores and other facilities. What is vertical groove vibration? What countermeasures are available? This section summarizes actual examples of improvements.

Walking vibration countermeasure for long-span floors
Spacious, open offices with long spans and no pillars are popular, but such long-span structures can cause the floor to sway easily when walking, which can lead to a poor working environment. In this document, we will explain why walking vibration occurs and how to prevent it. How can walking vibration be prevented? What kinds of floors have caused problems? Actual examples of long-span floor vibration countermeasures are explained and introduced in a comprehensive manner.
