The structural control system with vibration control device for non-structural reinforced concrete walls was proposed. This system is composed of X-shape steel plates embedded into the non-structural reinforced concrete wall. This steel plate deforms into plastic range proportionally to the lateral drift during an earthquake. This report presented the capacity of the structural system and hysteresis loops observed in the real size specimen under statically loading. And the method to estimate the initial stiffness and yield load of the structural system was proposed. In addition, earthquake responses of a reinforced concrete building with this device were analyzed based on the real size experimental results. As a result of the experiment, a good performance to absorb the input energy was obtained, moreover, the damage of this walls was slight. It was concluded that this structural system was able to control the lateral drift within a satisfactory range during severe earthquakes.
