چکیده

Application of multiple tuned mass damper (MTMD) can be a useful passive control method in the improvement of structural seismic behavior. In this paper, the effect of MTMD in reducing the response of reinforced concrete moment resisting frames under earthquake excitation is discussed. For this purpose, the structural peak displacement and the dissipated energy in the main structural members of several concrete moment resisting frames with and without MTMD have been investigated, and the results are compared. Structural modeling is done by using OpenSees software. The non-linear analyze is performed for several reinforced concrete moment resisting frames under earthquake excitations and the influence of MTMD on the structural behavior is discussed. The results indicate that generally effect of this system is significant to improve the seismic response of the structure and this system can be applied to design of the new structures or seismic retrofit.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
