چکیده
Abstract In recent years, the tuned mass damper inerter (TMDI) has been demonstrated in several theoretical studies to be an effective vibration absorber for seismic protection of non-isolated buildings. Its effectiveness relies on careful tuning TMDI stiffness and damping properties, while its performance improves with increase inertance property which is readily scalable. Nevertheless, all previous studies, energy dissipative element modelled by a linear viscous damper. Still, commercial dampers display nonlinear velocity-dependent power law behavior. this regard, paper investigates, first time literature, potential fitted (NVD) response multi-storey This supported efficient optimal (NTMDI) approach accounts any connectivity building structure employs statistical linearization treat term. For special case white-noise excited undamped buildings, NTMDI derived analytically closed-form shown sufficiently accurate lightly damped structures. Comprehensive numerical data are presented delineate trends NVD coefficient power-law exponent inertance. Further, history analysis results pertaining optimally application benchmark 9-storey steel demonstrate that reduced stroke force can achieved negligible change storey drifts floor acceleration adopting lower values, leading practically beneficial deployments.

Passive systems are preferred tools for seismic control of buildings challenged by probabilistic nature of the input excitation. However, other types of uncertainty still exist in parameters of the control device even when optimally tuned. The present work concerns optimal design of multiple-tuned-mass-damper embedded on a shear building by a number of meta-heuristics. They include well-known g...
