Abstract
Assessment of the tuned mass damper inerter for seismic response control of base‐isolated structures
Highlights
In order to reduce the vulnerability of civil structures against seismic-induced vibrations, an effective and widely employed passive control strategy is related to the installation of isolators between the structure and its foundation.[1]
Summary In this paper, the hybrid control of structures subjected to seismic excitation by means of tuned mass damper inerter (TMDI) and base-isolation subsystems is studied with the aim of improving the dynamic performance of base-isolated structures by reducing the displacement demand of the isolation subsystem
The seismic performance of TMDI hybrid controlled structures is investigated in a comparative study, considering simple isolated systems and systems equipped with other absorber devices such as the tuned mass damper (TMD) and the tuned liquid column damper (TLCD)
Summary
In order to reduce the vulnerability of civil structures against seismic-induced vibrations, an effective and widely employed passive control strategy is related to the installation of isolators between the structure and its foundation.[1]. In order to investigate on the influence of the nonstationary nature of real ground motions on the reliability of the approximated solution, the control performances of the base-isolated structure equipped with a TMDI are examined using different selected recorded accelerograms extracted by the collection of the 44 recorded far-field ground motions of the FEMA P-695-FF set.[31] in the previous analysis, a stationary white noise process was used as a model for base acceleration to derive the optimal design parameters with the minimal computational cost. The TMDI can be considered as an efficient means to improve the dynamic performance of base-isolation systems, especially for low-damped isolated structures (say with a damping coefficient of the base-isolation subsystem ζb < 10%)
