Abstract

Floors in a structure are often subject to periodic forces which induce excessive oscillations. For control of such oscillations, TMDs(Tuned Mass Dampers) have been widely used and prooved effective. But it is very difficult to estimate the natural frequency of a TMD when it is installed to a structure. Therefore to achieve the TMD properties that are required for satisfactory performances of the structure, it is necessary to tune the TMDs to the optimal state. This paper is intended to suggest the efficient tuning method for simple and economically designed TMDs and to investigate the validity of the method by installing TMDs to a real structure.
