Vibration Control of Structures with Initially Accelerated Passive Tuned Mass Dampers under Near-Fault Earthquake Excitation
This article deals with the applicability of passive tuned mass damper (PTMD) for reducing the dynamic responses of structures under near-fault earthquake excitations. Three types of pulse-like time functions are employed to simulate the near-fault ground motion. The vibration control effectiveness of PTMDs is extensively investigated through the comparisons of response spectrum and response ti...
متن کاملTHE CAPABILITY OF OPTIMAL SINGLE AND MULTIPLE TUNED MASS DAMPERS UNDER MULTIPLE EARTHQUAKES
The main focus of this research has been to investigate the effectiveness of optimal single and multiple Tuned Mass Dampers (TMDs) under different ground motions as well as to develop a procedure for designing TMD and MTMDs to be effective under multiple records. To determine the parameters of TMD and MTMDs under multiple records various scenarios have been suggested and their efficiency has be...
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 کاملreducing 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...
