Environmental Vibrations” that occur around us on a daily basis
What exactly is environmental vibration? What kind of problems does it cause? What should we do about it? Let us explain in an easy-to-understand manner.
What is Environmental Vibration?
It is the various vibrations that exist around us on a daily basis, mainly in buildings.
For example, have you ever felt this in a building?
- When large vehicles pass by the road near the building, you can feel the shaking...
- When I am working at my desk, I feel the floor shake when someone walks by me...
- Uncomfortable to feel the vibration of the construction work at the nearby construction site...
- When new production equipment machinery was installed in a factory, the floor started shaking...
- The floor below is a fitness studio and the floor can shake...
- When there is an event at a nearby live music venue, the house shakes...
- When you are inside a high-rise building during strong winds, the whole building is dizzy and shaking, and it is uncomfortable...
- There are stairs that sway so much that it is hard to walk on them when other people are walking...
- While shopping at the mall, I felt the floor shake when my child ran...
These are all environmental vibrations. Environmental vibration refers to all vibrations transmitted from various sources, both external and internal to the building, and is the vibration that we feel on a daily basis.
Classification of environmental vibration
Environmental vibration is classified into four main categories based on the direction and manner of vibration (steady/unsteady).
The direction of vibration is either vertical (up and down) or horizontal. The vertical direction is mainly floor vibration, while the horizontal direction is the shaking of the entire building.
Vibrations are classified into two types depending on whether there is temporal variation in the shaking or not: steady (shaking that remains the same all the time) and unsteady (fluctuating shaking).
The method of countermeasures and the expected effects will vary depending on where the vibration is categorized, so it is important to identify this when considering environmental vibration countermeasures.
Problems caused by environmental vibration
The magnitude of environmental vibration is so small that it is one or two orders of magnitude smaller than seismic tremors. Therefore, they do not endanger human lives by collapsing buildings or toppling furniture.
Most problems with environmental vibration are caused by the discomfort and uneasiness of the people in the building. We tend to think that we can just put up with it for a little while, but if left unchecked, it can lead to adverse effects on the body and mind. Above all, providing a comfortable living, working, and working environment is very important for improving building habitability and corporate productivity.
