The Tuned Mass Damper (TMD) is composed of a mass block, a spring and a damping system, the vibration frequency of the tuned mass damper is adjusted to be close to the main structure frequency, the structure resonance characteristic is changed, the damping effect is achieved, and the Tuned Mass Damper (TMD) is installed in a structure to reduce the energy dissipation requirement value of a basic structural component under the action of external force F. In this case, this reduction is accomplished by transferring some of the energy of the structural vibrations to the TMD which is comprised of a secondary mass-spring-damper cylinder system that is fixed or attached to the primary structure in its simplest form. Many of the early studies were limited to the use of dynamic vibration absorbers in mechanical engineering systems where the operating frequency was tuned to the fundamental frequency. However, environmental loads such as wind and earthquakes to which building structures are subjected have many frequency components, and dynamic vibration absorbers, commonly called Tuned Mass Dampers (TMDs), do not perform as well in complex and damped building structures.
