Abstract
Recently, the concrete-filled twin-layer steel-sheet composite wall systems (TSCWs) have become recommended by the engineers in the modern structures, since it has high energy absorption, ductility, and capacity compared to the corresponding conventional wall systems. Therefore, this paper presents and discusses the literature of researches particularly concerning this type of composite wall system. The review includes 80 papers that investigated the performance of TSCWs. These investigations classified TSCWs into two types: twin-layer flat steel sheet composite wall systems (TFSCWs) and twin-layer profiled steel-sheet composite wall systems (TPSCWs). The classification of these two types of TSCWs was based on the form of the sheeting as well as on the type of applied load. This classification introduced comprehensive mapping tables on the study details, loading, infill material, and interaction concept. Furthermore, the findings from this literature review are discussed, and the research gaps are summarized for each TSCW type, including the impact of providing an opening on the TSCWs performance.
Highlights
Steel plate shear walls (SPSWs) and reinforced concrete (RC) walls are commonly used as axial, cyclic, and impact resistance members in buildings, for instance, in mid-rise and high-rise structures
This type of study is highly recommended; future researches should investigate the effects of multiple shapes, sizes, and locations of openings on twin-layer steel-sheet composite wall systems (TSCWs) behavior under varied types of loadings mentioned in this study, as well as to determine the most proper, sufficient, and practical solutions that can rectify the implications of openings on TSCW behavior
A systematic review of the current state of the art of extensive investigations in the literature on TSCWs was conducted in this paper
Summary
Steel plate shear walls (SPSWs) and reinforced concrete (RC) walls are commonly used as axial, cyclic, and impact resistance members in buildings, for instance, in mid-rise and high-rise structures. The uncomplicated assembly of TSCWs due to their convenient components, which include an external twin layer of the steel plate and mechanical connectors filled with concrete, with or without a boundary frame, is an additional motivation for using these composites in more applications.
