For many years there has been considerable interest in the design of devices that, when added to an engineering system, will reduce significantly the vibration response. These devices have been implemented in a wide variety of structures, including tall buildings, bridges or machine foundations. The main disadvantage of a single TMD is its sensitivity of the effectiveness to the error in the natural frequency of the structure. The use of multiple tuned mass damper (MTMD) with frequencies tuned in the neighbourhood of the natural frequency of a structure improves the performance of the TMD. Optimum parameters of the MTMD used to reduce vibrations of construction and various tuning rules under different input function were examined by researchers.
