The most comprehensive analysis methods are nonlinear methods that require a lot of calculations. In this research, the Endurance Time method is used, which is a new dynamic method in which the need for calculations is reduced. In the Endurance Time method, the structures are subjected to specially designed acceleration functions and their response at different performance levels is estimated by each of the unit response history analyses, thus, significantly reducing the required computational demand. The design of these dampers in the studied structures was done based on the seismic performance index and with time history analysis using the Endurance Time method, and the sliding force of these dampers was uniformly distributed in the structure. According to the presented design method, as can be seen, by increasing the sliding force and making the dampers stronger, the performance index does not increase, and it is possible to distribute the dampers in a three-story structure with a sliding load of 15 tons and in 9 and 20-story structures with a sliding load of 10 tons and above were used uniformly in all stories, according to the averaging of the results. Also, in the base shear load, considering that the structure was a moment frame at the beginning and had a different target time, and then braces were added to it, as expected, the base shear values increased between 60 and 100 percent. Due to adding the damper to the system, taking into account the relative increase of input energy, as expected, the amount of dessipated energy is between 10 and 97%. In relation to the study of the drifts in stories, the reduction of the values in the stories was high, which was reported from 5 to more than 50% according to the results.
