A study on effectiveness of tuned viscous mass damper incorporated into reinforced concrete building

Although it is recognized that a tuned mass damper (TMD) is very effective in reducing wind-induced response of a structure, it is not in reducing earthquake-induced response. This is because a very large supplemental mass is required for seismic control of the structure. The authors have proposed a new seismic response control system, the tuned viscous mass damper (TVMD) that has an apparent mass amplifying mechanism to obtain a large supplemental mass effect enough to suppress earthquake-induced excitations. In this paper, the applicability and effectiveness of the TVMD to an inelastic MDOF system are illustrated by a design example.
