“…On the other hand, Cao et al Cao, Feng, and Wu (2014) investigated the influence of the TPSCW as a core of a reinforced concrete (RC) frame. To that end, 1/3 scale of One-bay, two-story samples were tested under cyclic load.…”

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.

“…Hysteretic curves and skeleton curves in the test and finite element are shown in Figure 5. The experimental data came from the test [9] and the finite element analysis came from literature [12]. By comparing the two results, it can be seen that finite element analysis curve trend were similar with the test.…”

“…The above results show that steel braces can work with RC frame to obtain good seismic performance. On the basis of existing research, Cao and Feng [9] proposed RC frames strengthening with profiled steel sheet bracing which takes the influence of infill walls into consideration. Through the experimental study, the feasibility of infilled RC frame reinforcing with profiled steel sheet bracing had been verified.…”

Seven infilled reinforced concrete (RC) frames strengthening with profiled steel sheet bracing are researched on the effect of axial compression ratio (0.3~0.9). Hysteretic curves, envelope curves, stiffness degradation curves, ductility and energy dissipation capacity are analysed in the finite element. The results show that profiled steel sheet bracing plays a good role in reinforcing infilled RC frames and the hysteretic curves express plump relatively. With the increase of axial compression ratio, the bearing capacity is improved significantly. The axial compression ratio has little effect on the lateral stiffness of the structure, and the initial stiffness increases slightly with the increase of axial compression ratio. The structure has good ductility when the axial compression ratio is less than 0.6. The ductility is declined with the increase of axial compression ratio. As the displacement increases, the energy dissipation capacity of the specimens increases. However, the energy dissipation capacity is reduced as the increase of axial compression ratio.

“…Xu, Fan, Lu and Li [23] proposed a new type of prepressed spring self-centering energy dissipation system (PS-SCED) that combines friction mechanisms between internal and external pipe components for energy supply. Cao, Feng and Wu [24] studied the seismic performance of reinforced concrete frames (RC) reinforced by steel bracing, which considers the effect of filler walls. Since the implementation of RCS connections of the through-beam is stronger than the connections of the through-column, therefore, in this research, a model will be investigated that in addition to ease of implementation, the resistance of the connection is not less than the connections of the beam type.…”

Frames consisting of composite reinforced concrete and steel (RCS) have been considered as structural systems for several years. This system benefits from the advantages of both systems by optimally combining steel and concrete structural elements. These connections are of two types, which include connections with a through-beam and connections with a through column. In this research, the laboratory model of previous studies has been simulated in ABAQUS finite element software and the seismic performance of RCS joints under cyclic loads and uniform loads was investigated. After validating the finite element model, a parametric study (checking the thickness of the steel panel in the joint area, checking the thickness of the cover sheet, etc.) was performed. Finally, after comparing the results of this type of connection, a modified model was presented which, in addition to increasing the capacity, shows a much more stable and desirable behavior.
