Abstract In this study, corrugated steel shear panels were applied to a metallic shear panel damper (SPD) to improve its seismic performance. The seismic performance tests and analysis of eight specimens were performed for different corrugated steel panel directions, arrangement forms, and material strengths. The results showed that the metallic corrugated shear panel dampers (CSPDs) exhibited remarkable plastic deformation and plump hysteretic loops. The direction of corrugated shear panels had the most significant influence on the energy dissipation performance, and the results of the horizontal corrugated direction exhibited the great performance. Then, the improved Bouc–Wen model was used to predict the hysteretic behaviour of the CSPDs, and the universal global optimization algorithm was applied to identify the model parameters. Additionally, a typical 12 storey benchmark steel frame structure was retrofitted with the CSPDs to verify the application effect of the CSPDs on structural vibration control. And the seismic fragility analysis was implemented to quantify the exceeding probabilities of different damaged states for the original structure and the damper improved structure. Compared with the benchmark frame, the performance level of the damper improvement frame in operation, immediate occupancy, life safety, and collapse prevention increased by 1.51%, 11.50%, 45.59%, and 81.19%, respectively, under the maximum considered earthquake (MCE) level. The analyses showed that the CSPDs could significantly improve the seismic resilience performance of the structure.
Highlights Corrugated steel shear panels were introduced to the traditional shear panel dampers. New corrugated shear panel dampers exhibits remarkable plastic deformation capacity and plump hysteretic loops. The directions, arrangement forms, and material strength of corrugated shear panels were analysed. The Bouc–Wen hysteresis model fits well with the hysteretic response of the CSPDs. Seismic fragility analysis was implemented to evaluate the seismic resilience of the frame with CSPDs.
