The four buckling resistance steel dampers were tested under cyclic lateral load to investigate the relationship of lateral load and displacement. The main variables are the existence of cover plate for preventing from buckling of out-of-plane and thickness of sim plate with 3.2 mm, 4.5 mm and 7.0 mm. The test showed that steel damper with cover plate had the wider area of its hysteresis loop than that of without.
