An equivalent single-degree-of-freedom model for the PTMD is developed and used to derive the equations of motion of the coupled PTMD-floor system. The optimal design parameters of the PTMD are found using an optimization algorithm.

To avoid excessive vibrations in towers, tuned mass dampers (TMDs) are often used as passive control devices due to their low cost. The TMDs can absorb part of the energy of vibration transmitted from the main structure. WebA tuned mass damper (TMD), also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce mechanical vibrations, consisting of a mass mounted on one or more damped springs. Its oscillation frequency is tuned to be similar to the resonant frequency of the object it is mounted to, and reduces the object's maximum …
