| Friction dampers are an effective way to reduce earthquake forces in concrete structures. The study examines the performance of three experimental Reinforced Concrete (RC) moment frames with different friction dampers. Two dampers had a transmission function, and one had a rotational function. After loading, their hysteresis diagrams were extracted and compared. In order to study the impact of slip force on the seismic performance of a concrete frame, numerical analyses were conducted. This section focused on a rotational damper that had demonstrated excellent experimental performance. At first, the friction damper was investigated numerically, and an approximate equation was proposed to calculate its sliding force. Similarly, following validation, the concrete frame equipped with rotational friction dampers was numerically analyzed. The analysis was performed using nonlinear static analysis, and the outputs of the model included resistance, ductility, energy dissipation, and stiffness. The experimental results demonstrated that, in terms of ductility, energy dissipation, and elastic stiffness, the rotational friction damper exhibited the best performance. Based on the numerical results, the best performance of the frame was obtained when the sliding force of the damper was equal to 1.4 times the strength of the bare frame. | ||
