| چکیده | ||
| In this study, an Active tendon control system is employed to reduce the dynamic responses of a two-dimensional frame. Different placement or arrangement of active tendons generates different structural responses. By means of optimization methods, the best placement and arrangement of controllers would be found, which leads to minimum dynamic responses and, eventually, the least cost of fabrication. To determine the number and arrangement of controllers in the two-dimensional frame that was considered both shear and non-shear manner, the genetic algorithm has been used, hence; to measure the controller force, four different algorithms, including Classic, Instantaneous, modal, and pole assignment has been applied, and a comparison has been carried out about the influence of these algorithms as the control algorithms. Furthermore, the time delay effect of the control force on the optimized number and locations of the controllers has been explored. Moreover, the effect of different responses of the structure, for instance, peak inter-story drift, absolute peak acceleration, or peak displacement as the variable of optimization equations, has been demonstrated. Besides, by examining different earthquake time histories and various levels of peak ground acceleration, in the structure case study, the influence of different dynamic loads was surveyed | ||
