Earthquakes are one of the most vulnerable disasters that effected many countries including India. Due to continuous ground motions caused by an earthquake structure gets damaged or even collapses causing human loss, property loss and psychological fear among humans. Many techniques available resist from seismic loads like base isolation devices, dampers, shear walls, outrigger structure, brace...

In this study, the tuned liquid damper (TLD) device was optimized by harmony search (HS) and adaptive algorithms (AHS). Using algorithm, seismic excitations were directed at single ten-story structures, TLD parameters to minimize building movement. To improve design parameters, optimization process repeated adapting factors of algorithm. For purpose, both memory consideration ratio (HMCR) fret ...

The major concern in the construction industry in constructing tall structures is vibration due to wind and earthquake. Tuned mass dampers are an effective and practical ways to reduce the effect of vibration in structures. This thesis presents a tool, which simulates the effect of tuned mass dampers on the structure. This tool has been proposed to form a part of the website, moment.mit.edu. Ja...

In this study, mass, stiffness and damping matrices of the Nosrat jacket; located in Persian Gulf; equipped with Semi Active Tuned Mass Damper (SATMD) system have been derived after modeling the structure in SACS software. Owing to huge number of the degrees of freedom in the model, computation of on-line control of SATMD was time consuming. For this purpose, the size of the model was reduced i...

In this paper, tuned mass dampers with optimal parameters for long span transmission tower-line system are investigated. Equations of motion for a structure-TMD system are derived, and the parameters of TMD, stiffness and damping are optimized, respectively. According to a real project, three-dimensional finite element models of both transmission tower and transmission tower-line system are cre...

The particle-tuned liquid damper (PTLD) can combine the functions of baffles and energy-dissipating materials, such as highly viscous liquids, by integrating particle dampers into a conventional tuned (TLD). However, particles distributed only at bottom container cannot drive motion water in middle layer to function effectively. Therefore, suspended (SPTLD) is proposed this study its effectiven...
