Abstract: This paper aims to investigate the hysteretic behavior of shear panel dampers (SPDs) made of mild steel Q235B incorporated in underground structures against earthquakes. Five SPDs were given cyclic shear loading tests, with the axial compression ratio and the web slenderness as test variables. The shear bearing capacity and the ductility decreased continually with increasing axial compression ratio. When the axial compression ratio exceeded 0.6, the hysteretic behavior was seriously affected. Cumulative energy dissipated by the test specimen with an axial compression ratio of 0.7 was only half that of the one with a ratio of 0.3. The control group (the SPD without the web) was set to estimate the horizontal resistance of upper and lower flanges that were mostly induced by flexure. The contribution of two flanges in resisting the shear deformation was about 15%.
