Abstract

Recent earthquakes in South Korea have resulted in various seismic reinforcements being developed with a focus on a building's seismic performance. Among vibration devices, Korea has been actively studying Steel Hysteretic Dampers due to its characteristics of having exceptional plastic deformation capacity and advantages in horizontal resistance in the instance of earthquakes. However, the disadvantages of Steel Hysteretic Dampers involve its difficulties during the application to three-dimensional shapes and its inability to serve as a reinforcement to buildings once the strut has been destroyed. This study proposes a damper model with twice the displacement along with the ability to secondary behavior after the strut has been destroyed and can be applied in its flat form. For this experiment, wooden structures were selected to apply reinforcement construction methods in situations where large deformations could occur. The results revealed there was a synergistic effect with the increase in strength for all specimens, and the possibility of preventing overturning through secondary behavior.
