In this study, a hybrid steel damper system using low-yield point steel and carbon steel was proposed in order to improve seismic performance of structure and prevent from out-of-plane buckling. Three cases of hybrid steel dampers were designed by setting the yield strength ratio of the low-yield point steel damper and carbon steel damper to 1, 1.5 and 2, respectively. Then, the hybrid steel damper with the minimum strength decrease ratio was selected using static loading test and finite element analysis. Nonlinear dynamic analysis was performed in evaluating the seismic performance of school building retrofitted with hybrid steel damper system. The school building retrofitted with a hybrid steel damper system showed an observable decrease in the interstory drift angle. And its top-level displacement response has reduced under three seismic waves. Finally, the hybrid steel damper system showed excellent energy dissipation capacity in terms of its stable hysteretic behavior and the seismic performance of school building was improved using hybrid steel damper system.
