Abstract: To explore the hysteretic behaviors of shear panel dampers under axial compression, numerical analyses were carried out using the general-purpose finite element software ABAQUS. Two important parameters, namely the axial compression ratio and the web slenderness parameter, were selected as governing parameters. To trace the material nonlinearity, a modified two-surface model was adopted to simulate the constitutive relations of the steel material under cyclic shear loading. Discussions focused on the hysteretic behavior, maximum shear strength, and energy dissipation performance concerning the axial compression ratio. It was found that axial compression deteriorates the hysteretic behavior and energy dissipation performance of shear panel dampers. In addition, under high axial compression, a small web slenderness parameter leads to unexpected brittle failure.
