This paper aims to investigate a new passive seismic energy dissipating device, circular shear panel damper (CSPD). There are several types of metal-based devices conceived as dampers for the seismic energy absorber whereby damages to the major structural components could be minimized for both new and existing structures. Steel dampers dissipate energy by inelastic deformation. Nonlinear FE simulation was conducted to evaluate the hysteretic behavior of CSPD. Different parameters are considered during analytical evaluation however; diameter-to-thickness ratio (D/t) is the main parameter as it is sensitive in the investigation of hysteresis performance. Depending on these parameters three different buckling shape and hysteretic behavior was found. Generally the CSPD can resist load in a large deformation without strength degradation.
