Abstract
In this research, the effect of different design criteria on performance of multiple tuned mass dampers (MTMDs) under earthquake excitation has been studied. For optimal design of MTMDs, the parameters of TMDs are determined based on minimizing an objective function. Two different objective functions including minimizing (a) the Hankel's norm; and (b) the maximum displacement of structure have been selected using Distributed Genetic Algorithms (DGAs) for solving the optimization problem. For numerical simulation, the method has been utilized on an eight-storey shear frame and optimal MTMDs have been designed. Results show that using the Hankel's norm as the objective function has led to design MTMDs which are effective in reducing the root-mean-square (RMS) of structural response under different earthquakes while in reducing the maximum response both design criteria have had the same results. Through numerical analysis the effect of design record, MTMDs mass ratio, TMD's number and stroke length on MTMDs effectiveness has been studied.
