Now constructs changes with each new day, all kinds of collections of beauty, art, creativity and engineering science and technology to create new century building that have sprung up everywhere. Show the exquisite technology.However, these tall, large-span or a cantilevered beam structure, susceptible to wind 、seismic forces or other special disturbance. Tuned mass damper (Tuned Mass Damper is called TMD), provides the most effective resistance excitation system. A variety of design configurations, and to follow the actual environment customized amended to meet the construction needs of the most economical.

Tuned mass damper (Tuned Mass Damper is called TMD), which consists of a mass, a spring and a damper attached to the different structure by Supported or suspended.

The theory of TMD was used the main structural which installed small mass、spring、damper to change that dynamic characteristic. TMD has been used to reduce the dynamic responses of structures under strong environmental loads which transferring the vibration energy from the structure into the TMD. TMD can reduce vibration when TMD Vibration frequency tune the same with main structural to resonance. Promote the structural safe and Comfort  

When structure vibration frequency and TMD itself vibration frequency same. The TMD for mitigating structural vibration using a TMD involves transferring the vibration energy from the structure into the TMD, which dissipates this energy through the damping effect. Vibrational structure becomes small, but the vibration of TMD (displacement) will enlarge. So we want to install some extra vibration dampers to dissipate the energy of TMD. Like the door upload as many as those damper. Because the damper force is applied to the door.So the door will "slowly" closed

The TAIPEI 101 wind damper is actually one kind of the tuned mass damper (TMD) under simple pendulum system. Vibration period determined by adjusting the length of the pendulum (It has nothing to do with the weight on the pendulum).The longer the pendulum’s length, the longer vibration period it is, and vice versa .Since skyscraper usually has longer vibration period, TMD’s length of the pendulum must long enough to be adjusted tune the construction.
