Improves the environment by reducing unpleasant shaking! Vibration Damping Device TMD
[Scenes of use]
Vertical (up-and-down) vibration countermeasures for office buildings and commercial facilities, such as floor swaying, cross corridors, eaves, etc.
- When installed at locations with vibration problems, the reaction force of the weights suppresses shaking.
- It is effective for everything from bothersome vibrations such as walking and equipment to large vibrations such as earthquakes.
- The TMD base is installed by bolting together the small beam and the TMD base. No structural changes to the building are required, and the design is not compromised because it is hidden behind the floor.

- The large overhanging eaves also provide earthquake protection without changing the design!
- Reduces unpleasant vibrations in crossing corridors!
- Realizes a comfortable office environment! Prevents walking vibration on long-span floors
- Avoid vibration problems caused by multiple people exercising in a fitness studio!
- Concerned about floor shaking caused by operating vacuum pumps! Improve the working environment of your factory

Measures can be taken even after occupancy! Ultra-Thin Vibration Damping Device Floor Mate
[Scenes of use]
Floor swaying in offices (walking, traffic vibration, etc.), vibration control for stairs, etc.
- Ultra-thin design fits under OA floors.
- Installation is simply by placing it under the panel, making it ideal for addressing vibration issues after occupancy.
- Its low profile allows it to be installed under stair treads and landings. It is also effective when installed at an angle.

How to achieve both design and vibration control
Buildings are required to be not only comfortable but also well designed, but they tend to have long spans, no pillars, and other structures that are prone to vibration. This section introduces measures to reduce vibration while ensuring design quality.
Vibration control for existing buildings "after the fact
Increasingly, vibration problems are occurring later due to layout changes, changes in use, and new installation of equipment and machinery. However, the usual vibration control measures would require large-scale construction work. This section introduces the features and installation examples of Yacmo's vibration control system, which enables "after-the-fact" vibration control measures for existing buildings.

Small size solves a wide range of floor sway problems! AMD Vibration Damping Device
[Scenes of use]
Floor vibration in offices (walking, traffic vibration, etc.), equipment and machinery vibration in factories, vertical vibration control in fitness clubs, etc.
- Because it is motor-driven and has a large thrust, it is smaller and more effective than a TMD.
- Covers a wide range of vibration, from floor shaking in offices to large vibrations in factories
- Compact size allows installation in available space. It is perfect for vibration control later on.

Comfortable and secure even in strong winds and earthquakes! Horizontal TMD/AMD
[Scenes of use]
Wind sway, traffic vibration, and earthquake protection for mid-rise and slender buildings.
- Various anti-rolling measures are available. Quickly reduces swaying and is effective against post-earthquake swaying.
- Since it is simply installed on the rooftop or upper floor, it can be used effectively without disturbing the space inside the building.
- The size of the weights varies from several tens of tons to over 100 tons depending on the subject of the shaking to be suppressed.

Introduction of Horizontal TMD
Features and installation examples of horizontal TMDs that reduce lateral sway from earthquakes, strong winds, and traffic vibrations are introduced.
Protecting Buildings and Occupants with "Earthquake Resistance + Vibration Damping
Seismic countermeasures alone may result in large interior shaking that may cause human casualties, or damage that may cause the building to not last long. The following is an easy-to-understand summary of common misconceptions about earthquake resistance and the advantages of combining earthquake resistance and vibration control.
Wind sway countermeasures for mid- and high-rise buildings increase occupant performance!
Wind sway can be a problem not only in skyscrapers but also in long, narrow mid-rise buildings that are built on narrow lots in urban areas. This section introduces the causes of wind sway in mid-rise buildings and examples of horizontal TMD installations that are effective as wind sway countermeasures.
