reducing the seismic response of nonlinear hysteretic structures using optimal multiple tuned mass dampers
in this research, the effectiveness of multiple tuned mass dampers (mtmds) in mitigating the response of nonlinear hysteretic structures has been studied where the optimal parameters of mtmds have been determined based on minimization of maximum relative displacement (drift) of structure. for solving the optimization problem the genetic algorithm (ga) has been used successfully. for numerical a...
متن کاملdual-layer multiple tuned mass dampers for vibration control of structures
the performance of dual-layer multiple tuned mass dampers (dl-mtmd) with uniformly distributed natural frequencies is investigated. the dl-mtmd consists of one large tuned mass damper (l-tmd) and an arbitrary number of small tuned mass dampers (s-tmd). the primary structure is represented as a single degree-of-freedom system which corresponds to a specific vibration mode to be controlled in a r...
متن کاملSemiactive Tuned Mass Dampers
Studies have already demonstrated the successful use of linear semiactive damping devices, such as variable orifice (VO) dampers, for semiactive TMD systems. More recently, nonlinear semiactive damping devices, such as magnetorheological (MR) dampers, have also been shown to be effective for semiactive control of TMDs. Though semiactive dampers differ widely, with responses ranging from linear ...
متن کاملEfficacy of Tuned Mass Dampers for Bridge Flutter Control
This paper examines efficacy of tuned mass dampers ~TMD! in controlling self-excited motion resulting from negative damping. New optimal TMD parameters are suggested which provide better performance than those suggested in the literature. The dependence of TMD performance on structural damping is highlighted. The equations of motion of a combined system comprised of multiple TMDs attached to a ...
متن کاملWavelet PSO-Based LQR Algorithm for Optimal Structural Control Using Active Tuned Mass Dampers
This study presents a new method to find the optimal control forces for active tuned mass damper. The method uses three algorithms: discrete wavelet transform (DWT), particle swarm optimization (PSO), and linear quadratic regulator (LQR). DWT is used to obtain the local energy distribution of the motivation over the frequency bands. PSO is used to determine the gain matrices through the online ...
