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.‎
