Unwanted vibrations or high amplitudes occur in the structures with the effect of seismic excitation such as earthquakes. These vibrations and amplitudes have destructive effects on the structure as well as reducing the comfort of the structure. For this reason, it is an important task of structural engineers to make the structure more stable at the time of an earthquake by adding different control systems. In this study, an active tendon control system with Proportional Integral Derivative (PID) controller is used in a single degree of freedom system (SDOF). The parameters of the PID controller are determined by the Jaya Algorithm (JA), which is one of the metaheuristic algorithms. The optimum parameters are calculated as a result of 10000 iterations. Then, these parameters have been investigated for the effect of the active tendons on the structure when the mass of the structure increases by 5, 10, 15 and 20 % due to the change of live loads. As a result, the optimum results are an effective approach to find the optimum parameters of active tendon-controlled structures under seismic excitation.
