In this study, based on the research results of the steel plate and steel rod dampers with rocking behavior, the moment and the drift ratio were compared and evaluated. As a test result evaluation, it was showed that the behavior of R15-200 and R15-140 was very good than other dampers. And the steel rod damper showed in-plane behavior to the loading direction, and was evaluated to prevent out-of-plane behavior that causes performance degradation.

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.
