Optimization of three-element tuned mass damper for single degree of freedom structures under ground acceleration; [Yer ivmesi etkisi altındaki tek serbestlik dereceli yapılar için üç elemanlı ayarlı kütle sönümleyicinin optimizasyonu]

Passive control devices have been used for a long time to reduce unwanted vibrations. The most commonly used of these devices are tuned mass dampers. The optimum parameters of the three-element tuned mass damper for damped main structures due to ground acceleration are investigated in this paper. Unlike the traditional tuned mass damper, the three-element tuned mass damper contains two spring elements and one of them is connected in series with the damping element. The optimum parameters are obtained by simulated annealing algorithm. Numerical results show that the three-element tuned mass damper is very effective in reducing dynamic vibrations of the damped structures.
