Tuned mass damper inerter for seismic control of multi-story buildings: Ten years since inception

Abstract

The tuned mass damper inerter (TMDI), devised by combining a conventional tuned mass damper (TMD) with an inerter, is believed to be a significant advancement in the realm of seismic vibration control. The chief advantage of the TMDI over the conventional TMD is that, through the realization of the mass amplification property of the inerter, the TMDI can be designed as a highly efficient dynamic vibration absorber with a notably reduced mass. Further, unlike the conventional TMD, the TMDI exhibits its ability to dampen the higher modes of vibration, which sometimes become crucial during seismic vibration control of multi-story buildings. The TMDI is also more robust against potential mistuning. Owing to these distinct features, the TMDI has steadily gained prominence amongst researchers over the last decade, since the publication of the first paper on this topic in the year 2013. A large volume of research has been devoted to the study of the seismic vibration control of multi-story buildings using the TMDI. These studies deal with the design, optimization, and performance assessment of the damper system through frequency domain, time domain, and experimental studies. Attempts have also been made to develop innovative configurational variations of the TMDI and to use the TMDI in conjunction with other dampers as a hybrid system. Such rapid and multi-directional growth in research on the TMDI, and the need to examine its future prospects in the aseismic design of multi-story buildings, necessitates an in-depth review of the works on this topic, which is found missing till date. The current work thus provides a structured review of the development in the field of TMDI-assisted seismic vibration control of multi-story buildings during the last ten years and identifies the future research directions in the field.
