Inelastic Cyclic Behavior of C-Shaped Composite Plate Shear Walls - Concrete Filled

This research project was conducted to investigate the cyclic lateral load behavior of Composite Plate Shear Wall/Concrete Filled (C-PSW/CF), in terms of strength, and drift capacity. The testing program includes two large-scale C-shaped concrete filled composite plate shear core walls subjected to flexure and axial loads together. Their dimensions were the same, but different axial loads were applied up to 19% of axial loading capacity. The composite behavior and inelastic response were investigated and compared to results from plastic moment calculations. This provides valuable results on the expected behavior of one composite cross-section that is frequently used in full core wall. This was done to support the development of design guidelines for high-rise core-wall steel buildings having C-PSW/CF as the primary lateral force resisting system.
