In this study, a rocking behavior experiment using a guide plate and a guide channel to prevent lateral deformation of a steel damper was planned. For this purpose, strut I-type specimen I-1 and strut S-type specimen S-1 were prepared. The experimental results were compared with the existing experimental results of SI-260 and SS-260 under the same conditions without the details of lateral deformation prevention in order to evaluate the effect of preventing lateral deformation. The damper with lateral deformation prevention detail was evaluated to have superior strength capacity, deformation capacity, and energy dissipation capacity than the damper without it. Therefore, the lateral deformation prevention detail was evaluated to have a good effect in improving the design capability of the steel damper.
