This paper concerns the numerical performance evaluation of multi-degree-of-freedom systems equipped with Tuned Mass Dampers-Inerter (TMDIs); a passive control device used for mitigation mechanical vibrations induced by dynamic loads. The inerter is commonly to increase apparent mass classics tuned dampers (TMDs), improving its seismic performance. To evaluate TMDI action, three case studies ar...

The aim of this study is to compare the seismic response reinforced concrete (RC) symmetric buildings, with a varied number stories, strengthening three types passive energy dissipation systems, as tuned mass dampers, viscous and friction dampers. paper presents an overview design optimization object minimizing certain functions: (i) maximum displacement at top structures, (ii) base shear loads...

A tuned mass damper with variable stiffness can achieve vibration reduction without changing the resonant frequency, but large limits its engineering applications. To overcome this drawback, a novel is proposed adjusted by PI controller and block replaced an inerter. The attached to two-degrees-of-freedom primary structure, dynamic equations are established. frequency responses obtained from ha...
