The H<sub>2</sub> and H<sub>∞</sub> norm of roof displacement transfer function are implemented and compared as the objective functions under Near-Fault (NF) and Far-Fault (FF) earthquake motions. Additionally, the consequences of different characteristics of NF ground motions such as forward-directivity and fling-step are investigated on the behavior of a benchmark 10-story controlled structure. The Colliding Bodies Optimization (CBO) is employed as an optimization technique to calculate the optimum parameters of the TMDs. The resulting statistical assessment shows that the H<sub>∞</sub> objective function is rather superior to H<sub>2</sub> objective function for optimum design of TMDs under NF and FF earthquake excitations. Finally, the robustness of the designed TMDs is evaluated under a large set of natural ground motions.</p>}, number={3}, journal={Periodica Polytechnica Civil Engineering}, author={Kaveh, Ali and Farzam, Mazyar Fahimi and Maroofiazar, Rasool}, year={2020}, pages={828–844} }
