کنترل بهینه یک ساختمان ده طبقه با میراگر جرمی دوگانه به همراه اینرتر با استفاده از الگوریتم جستجوی پرنده گریزان

Application of tuned mass damper with inerter has recently been introduced. However, embedding such a system to lower stories brings about some architectural problems. In the present work Double-TMDI is introduced instead; in which, two masses are connected with the inerter. The system parameters are obtained via an optimization process. That is minimizing infinity-norm of the inter-story drift as the objective function. The optimal design task is accomplished by utilizing two methods for the problem: the escaping bird search as a recent meta-heuristic and the particle swarm optimization as a well-known trusted algorithm. The proposed escaping bird search is found successive in solution of the problem showing superior performance over the popular particle swarm optimization regarding both the efficiency and the effectiveness. By evaluation of the resulting drifts in the system with Double-TMDI versus, ordinary TMDI and TMD, it is observed that the proposed optimal DTMDI can better reduce structural responses. Consequently, the structural safety for residential application is improved. It should also be indicated that using the proposed system, the architectural challenges are avoided.
