Abstract

The authors have presented a new seismic control device the Tuned Viscous Mass Damper (TVMD). The TVMD consists of a viscous mass damper with an apparent mass amplifier and a soft spring which connects the damper to the primary system. The mass amplifier allowed us to make the additional mass and device itself smaller compared with a conventional TMD. The design method to determine an optimum set of damper parameters has not yet been presented for a vibration control system of a damped MDOF structure, while that of an undamped SDOF structure is obtained by the fixed point theory. In this paper, we present a design method to obtain a set of optimum damper parameters for a seismic control system of a damped MDOF structure using sequential quadratic programming (SQP).
