In this study, the Tuned Mass Damper (TMD) optimization is carried out to reduce resonant motion of Submerged Floating Tunnel (SFT) under wave excitations. The SFT dynamics evaluated in frequency domain; a new approach cost-effectively optimizing TMD parameters for moored system suggested. Discrete-Module-Beam (DMB) method used model Tunnel; mooring lines are included as equivalent stiffness ma...

Tuned mass damper inerter (TMDI) is commonly reported to be a lightweight tunable device that can significantly reduce buildings' seismic response. However, the backward action produced by and returned building in conventional TMDIs may either performance or limit potential. This study proposes investigates novel control scheme using large physical ratios generated inerters. Hence, double tuned...
