Seismic Performance Analysis of Replaceable Corrugated Steel Plate Composite Shear Walls Based on Interaction Relationships

Replaceable systems, including the main structure and components, are the primary means of building a resilient city. However, due to the complex interaction relationships, the energy‐dissipation effect of such structural systems is not ideal. Accordingly, this study used a replaceable corrugated steel plate composite shear wall as an example, focusing on the seismic performance and energy‐dissipation ratio analyses of each component. We attempted to find a suitable stiffness ratio index to determine the interaction relationship of the replaceable corrugated steel plate shear wall. An energy‐dissipation evaluation method is proposed based on the stiffness ratio index, and the bearing‐capacity formula of the shear wall was modified. The results show that the revised lateral‐bearing‐capacity formula based on the energy dissipation evaluation exhibited ideal accuracy and could provide a reference for practical engineering applications.
