In the previous studies, hysteretic performance of the damper of shear panel type using low-yield-strength (LYP) steel, which has about 100 N/mm^2 of yield strength, under static shear loading were verified through cyclic loading tests. Other strength types of steel also have been utilized for panel damper. In this study, three different strength types of steel : two types of LYP steel (LYP100, LYP235) and normal mild steel (SS400), are selected for shear panel of the damper. Six specimens of square panel, whose width-thickness ratios are 22, 33 and 50 respectively, were tested under static and cyclic shear loading without axial force. As the results of the test, specimens of lower strength type of steel that also had smaller yield strength ratio showed higher energy dissipating capacity. In consequence, it is understood that hysteretic performance of the panel damper with different strength type of steel, such as maximum strength, permissible deformation capacity and hysteresis rule, are well estimated by the empirical formula obtained from the previous studies on LYP100 steel panel dampers.
