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.

“…The final mode, on the other hand, takes place when an infill wall is subjected to ground shaking transverse to the plane of the wall. The present study is dedicated to the influence of the strengthening method developed by Aykac and his companions (Aykac et al, 2014;Aykac et al, 2013;Kalkan et al, 2013) on the out-of-plane flexural behavior of hollow brick infill walls. FEMA 306 (FEMA 1998) states that out-ofplane failure of infill walls is generally unlikely to take place except the infill walls at high stories of a structure.…”

“…Aykac and his companions (Aykac et al, 2014;Aykac et al, 2013;Kalkan et al, 2013) conducted an extensive research program on an innovative strengthening technique for masonry infill walls. In this technique, perforated steel plates are bonded to both faces of the wall and connected to each other and the wall with the help of post-tensioned bolts.…”

The brick infill walls cease to contribute to the lateral strength and stiffness of a structure as soon as they fail in a brittle manner in the early stages of an earthquake. Recent studies indicated that the perforated steel plates externally bonded to both faces of a wall lead to two benefits. First, the increase in the lateral strengths and rigidities of the walls increase the overall lateral strength and stiffness of the structure. Secondly, the increase in the ductilities of the walls allows the walls to absorb higher amounts of the earthquake-induced energy before failure so that smaller amounts of energy are required to be absorbed by the bearing structural members. The present study is dedicated to investigate the efficiency of this technique on the behavior of brick walls under out-of-plane bending moments, induced by the blast effect of an explosion or pressure from the soil, wind or snow next to the wall. A brick wall strengthened with perforated steel plates and a brick wall strengthened with perforated steel plates and steel strips on both faces were subjected to four-point bending. The steel plates greatly contributed to the bending capacities of the walls. The use of steel strips on the plates did not affect the flexural capacity of the wall, while increasing the ductility of the wall considerably.

“…In search for an economical, easy-to-apply and convenient method, steel strips, profiles and plates were utilized in a number of studies (Taghdi et al, 2000;Farooq, Ilyas and Ghaffar, 2006;Ozbek and Can, 2012;Aykac et al, 2014;Kalkan et al, 2013;Ozbek et al, 2014) for strengthening infill walls. Aykac and his companions (Aykac et al, 2014;Kalkan et al, 2013;Ozbek et al, 2014) proposed the use of perforated steel plates for strengthening hollow brick infill walls and conducted a series of tests on the wall specimens. Perforated steel plates were adopted due to their following advantages and superiorities over the existing strengthening materials and methods:…”

“…These perforations also avoid any possible damage for the water and sanitary fixtures in the wall if the locations of these fixtures are marked on the wall before drilling the holes The present paper summarizes 14 experiments conducted within the third stage of an experimental program (Ozbek et al, 2014). In the first stage of the program, individual brick wall specimens were tested under monotonic diagonal loading (Aykac et al, 2014), similar to the loading condition of infill walls in the case of lateral seismic loading. Based upon the promising results obtained in the first stage, individual wall specimens were tested under reversed cyclic lateral loading in the second stage (Kalkan et al, 2013).…”

The Strengthening of the non-bearing elements of a structure not only increases the overall lateral strength and stiffness of the structure, but also causes a major amount of the earthquake energy to be absorbed by the nonbearing members and therefore reduces the risk of damage in the structural components. The present paper focuses on a number of experiments carried out within an extensive research program, investigating the influence of strengthening the brick infill walls of an RC frame with perforated steel plates on the seismic behavior of the frame. Perforated steel plates are adopted in strengthening due to their several advantages including the great ductilities and deformation capacities of these plates, the fire resistant, recyclable and non-cancerogenic nature of steel and the ease of application of this technique. A total of 14 half-scale specimens, each composed of a strong foundation, two columns, a beam, and a brick wall, were tested. Plate thickness, bolt spacing and plate-column connection were chosen as the test parameters. The observations from previous experiments conducted on individual brick wall specimens were used for detailing the strengthening plates and the plate-wall connections. Additional column and joint strengthening applications provided significant improvements in the seismic behavior of the specimens.
