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.
