In this study, an innovative corrugated steel plate shear wall with additional dampers is proposed, in which dampers exhibiting excellent energy dissipation performance are installed at the bottom plastic hinge areas of the shear wall. Seismic performance of the innovative corrugated steel shear walls is compared to that of traditional ones. The failure mode, hysteretic behaviour, strength and cyclic degradation behavior, ductility and stiffness behavior, and energy dissipation behavior of the shear walls are analyzed and further discussed. Then, 3D finite element models are implemented to investigate the energy distribution mechanism of the innovative shear wall. The results demonstrate that the installation of the dampers significantly increases the lateral stiffness and energy dissipation performance of the innovative wall compared to the traditional wall. In addition, the energy dissipation matching model between the corrugated steel plate and the dampers is established through numerical simulation analysis. Finally, the traditional shear capacity equation is supplemented to consider the contribution of the embedded corrugated steel plate separately from that of the frame with dampers. •An innovative corrugated steel plate shear wall equipped with replaceable bottom corners dampers is proposed.•The comparisons of seismic performance were conducted for the innovative and the traditional corrugated steel shear walls.•The energy dissipation matching model between the corrugated steel plate and the dampers was established by FEA analysis.•A simplified equation is recommended for evaluating the shear capacity of the innovative corrugated steel plate shear wall.
