A combined damping device combining two types of damping devices is being developed to cope with various magnitude of earthquake. Thus, in this study a wall-type hybrid damping device that combined with a steel slit damper and rotational friction damper was proposed and the reinforcing effect was analyzed through a real RC-frame experiment. As a result of the real RC-frame experiment, stable hysteresis behavior was performed within the story drift ratio corresponding to the target performance and the maximum strength of the reinforced specimens was greater than that of the non-reinforced specimen. Cracks in reinforced specimen appeared to be smaller than non-reinforced specimen, and the amount of energy dissipation was also greater than that of non-reinforced specimen. Comparing the results of the precision structural analysis, the hysteresis was similarly simulated, but the hysteresis after yielding point was different from the experimental results that the analysis results showed a ductile behavior.
