DESIGN OF STEEL-PLATE CONCRETE COMPOSITE WALL PIERS

The lack of analysis, design and detailing guidance in standards and manuals has contributed to the limited use of steel-plate concrete (SC) composite shear walls. In this paper, a process to design SC wall piers is proposed, which accounts for wall aspect ratio, faceplate reinforcement ratio, axial force, and concrete and faceplate strengths. The mechanics-based equations are used to generate axial force-bending moment interaction curves for different material properties and aspect ratios. The proposed design equations may be suitable for inclusion in a seismic design standard.
