Hybrid Coupled Walls (HCW) are comprised of two or more reinforced concrete wall piers
connected with steel coupling beams distributed over the height of the structure. Extensive
research over the past several decades suggests that such systems are particularly well suited for use in regions of moderate to high seismic risk. This paper reviews the state-of-the-art in seismic modeling, analysis and design of hybrid coupled wall systems. Design methodologies are
presented in both prescriptive and performance-based design formats and a discussion of alterative types of hybrid wall systems is provided.
