In recent years, steel plate shear wall (SPSW) systems have been used in steel structures to withstand lateral loads in areas of high seismic activity. A single seismic resistance device is often not economical to withstand lateral earthquakes and wind loads. In these cases, vibration control methods with a high capacity for energy dissipation must be used to minimize structural deformation and damage. Because of their simplicity and lack of external power needs, passive control devices have been used successfully for many years for vibration mitigation of a wide variety of structures, ranging from simple beams to complex space constructions. The current study aims to demonstrate the seismic behavior of a novel lateral load resisting device that combines a viscoplastic damper, i.e., a Rubber-Steel Core Damper (R-SCD), with a shear wall of a steel plate. A passive hybrid viscoelastic damper consists of a rubber layer with high damping properties and ductile steel cores. Finite element models of SPSW fitted with R-SCD viscoplastic dampers are investigated using Abaqus software to evaluate the innovative damper and its effect on the seismic behavior of SPSW. The results show that the proposed dampers can act as a fuse and keep the main members of the structure in an elastic state without damage. Also, after applied load, the damper bolts, which play a major role in the energy absorption of the structure, become deformed and inelastic so that they can be easily replaced. Therefore, it can be said that the system has a cost-effective replacement property. The system's final capacity and energy dissipation are directly increased by increasing the number of steel bolts used in current dampers. In the present study, it has been shown that the diameter to high ductile reign ratio (d/h) of the bolts, Rubber thickness, how the damper is connected to the shear wall, and bolts properties are the most critical factors in the seismic behavior of the system.
