“…The Four-point bending test procedure was conducted, and the flexural capacity of the experiment is considered sufficient to be categorized as the primary beam. Furthermore, Salih et al [15] was investigated a lightweight steel composite beam. The beam configuration was installed through-bolts to connect the lipped channel back to back (I-shape) and toe to toe (box-shape).…”

“…The flange cleats are often used to reinforce the joint in the existing structure. The investigation of concrete slab combines with cold-formed steel as the primary beam was conducted [11][12][13][14][15]; the purpose of those study is to find out the behaviour of the cold-formed component within the slab shear connector configuration [11,12,15] and beam variation [13,14].…”

Cold-Formed Steel (CFS) is lightweight steel produced by forming the thin plate in cool condition. It became widely used for any purpose of household furniture and light construction elements from the middle of the twentieth century. CFS could be used as purlin, roof cover, steel truss, wall panel, composite deck slab, and structural framing. One of the disadvantages is the buckling problem which reduces the maximum load. The development of technology leads to the massive product of CFS. CFS became more popular and well-accepted in any region in the world [1].

“…The result of the study stated that the composite joint had a higher ultimate load capacity and higher moment resistance than the non-composite connection. Firdaus et al [20] The composite beam with CFS material was investigated by Salih et al [17]. The configuration of the beam was installed with the bolts connection through I-shape and box-shape.…”

“…The purpose of additional flange-cleat is related to quick and easy installation and avoids the welding process, which is expensive. Some research combines the composite slab with CFS as a primary beam [13][14][15][16][17].…”

Cold-formed steel (CFS) is currently used as the alternative material of Hot-Rolled Steel (HRS). One of its benefits is that the CFS has a lighter weight rather than HRS. The CFS is produced by forming the thin plate into some type of section at room temperature. CFS is beneficial in daily life; it could be used as the purlin, roof truss, roof cover, composite deck slab, wall panel, racking, and structural framing. Due to its advantages, the demand for CFS usage in construction works increases significantly, so CFS production becomes more massive [1]. On the other side, the CFS has disadvantages; it is instability because of the thin plate behavior. The CFS section tends to buckle when it is subjected to a more significant load [2]. *Author for correspondence Several type connections could be utilized for the beam-column connections of CFS. It commonly uses the screw as the connector to connect the roof truss component of the CFS because it is quick and straightforward in installation. In the primary structure connection, such as beam to column connection, the screws connection has some installation problems. The strength to resist the load in the structural component is deficient. So, the proposed bolted connection with slip-in gusset plate on beam-column connection is conducted in this study. There are few studies about the non-composite connection research of CFS as the structural component, which is a beam-column connection [3-7]. Aminuddin et al. [3] has studied rectangular slip-in gusset plate configurations with rectangular shapes for the bolted connection. It continues to make another connection by combining the flange cleat with a

“…However, if the beam is encased partially with concrete and fitted with rebars at the tension area, it can increase strength and stiffness. The development of research on CFS composite beam technology with partial encasement continues [3][4][5][6][7][8][9][10][11][12] to show that the section of the composite beam with encased partially provided ductile flexural action for the composite beam. In contrast to solid slabs, the use of Push-out Test of Profiled Metal Decking Slabs Achmad Abraham S. ARMO et al http://wjst.wu.ac.th profiled metal decking slabs in the composite beam is becoming more common for multi-story buildings because it allows for large spans with little or no scaffolding.…”

New methods to provide shear strength on the cold-formed steel (CFS) lipped c-channel section composite beam encased with concrete partially is proposed using rebars embedded in concrete. The development of research on the CFS composite beams technology with partial encasement shows that the section of the composite beam encased with concrete partially can provide ductile flexural action for the composite beam. The application of profiled metal decking slabs in the composite beam is becoming increasingly popular compared to solid slabs. However, it has a detrimental effect on the structural behavior of a composite beam. This research is aimed primarily at presenting the behavior of the rebar shear connector to evaluated ductility, shear capacity, and modes of failure. Two samples using a rebar 12 mm in diameter in the profiled metal decking slabs and solid slabs were tested using the standard push-out test till failure. For the composite beam design, the proposed shear connector embedded in the slab concrete and the CFS encased with concrete partially used the test results’ shear capacity, greater than the values as proposed by section 3.1, BS 5950. Due to rebars shear-off, the solid slab specimen failed with the highest load of 489.6 kN while the Profiled Metal Decking Slab specimen failed due to the formation of the cracks on the PMDS at 421.1 KN ultimate loading. HIGHLIGHTS A new system of the rebar shear connectors for the Cold-Formed Steel (CFS) composite beam partially encased in concrete have been developed The main purpose of push-out testing is to investigate the shear capacity and ductility of the proposed shear connector failure modes and load-slip connections The shear capacity of the test results is greater than the values as indicated by BS 5950 Part 3.1 The proposed rebars as a shear connector for partly embedded CFS can be used in the construction GRAPHICAL ABSTRACT
