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...

abstract: appealing to the principle of vertical residence and stemming the horizontal expansion of the city, the tehran milad tower is being built on 35000 sm3 site with the total area of 220000 sm3. with a height of over 170m, this 56-story concrete building is in the final stages of construction and would be the highest residential building of iran. since tehran is located in a high-risk ear...

This paper aims to introduce two new adaptive designs of vibration control systems. First is an absorber and the second is an isolator. Absorbers are used for suppressing unwanted vibrations, while isolators isolating them. Structural parameter changes and excitation directions significantly affect the behavior of the conventional passive controllers. A Tuned Stiffness Damper (TSD), stepper mot...
