“…Ghannam [2] done on C section connected back to back in which DS(Direct strength) and EW(Effective width)gave a conservative result for bending moment capacity also more experimental works are required to compensate for the lack of data in this field study. Serror et al [13] experimented with C sections connected back to back and Hassan et al [16] done numerical prediction on C section, curve section and broken section connected back to back found that the C section is in need of stiffeners to enhance ductility. Wang and Young [14] investigated C sections connected back to back using screws with intermediate stiffeners and found that the numerical and experimental investigation are good in terms of ultimate moments, failure modes and the moment-curvature behaviour.…”

Abstract. Cold-formed steel, thin-walled steel product finds a wide application in construction worldwide. It has many advantages such as flexibility, convenient handling and fabrication and so on. The CFS is commonly used in structures like bridges, railway coaches etc., as it is economical when compared with hot-rolled steel. It can be used as single or built-up flexural members. Generally, the open section beams are susceptible to failure by lateral- torsional buckling due to the position of its centre of shear and centroid of the cross-section. To overcome this issue, open doubly-symmetric built-up sections or built-up closed sections have been used by many researchers. The parametric studies were conducted by many researchers to find the accuracy of the design strength predictions of the built-up beams. In parametric study, Eurocode specifications, the direct strength method and effective width method based on the North American specifications were used. The study reveals that there are no proper design guidelines available in the current Eurocode and North American specifications. Therefore, the paper provides an outline of research works done on various CFS sections by the researchers and their proposed design recommendations to the codal specifications were also reviewed.

“…Nevertheless, with the advancement in construction industry, the significance of CFS became more visible in the construction field with noticeable advantages such as cost-effectiveness, lightweight, easy installation, low maintenance and corrosion resistance, easily transportable, recyclable, and easy fabrication. CFS is introduced to the construction industry through its high strength to weight ratio, long-lasting versatility, stability, safety and cost-effectiveness [1]. In addition, CFS have been known to contribute significantly to the environment and maintain green construction in the formation of low-rise residential and medium-rise commercial structures [2].…”

Cold-formed steel (CFS) built-up sections have been recently introduced with other materials such as concrete connected by means of bolting and screws to avoid the problems of the CFS sections buckling. The flexural analysis of CFS-concrete composite beam is more complicated in terms of design and failure mode. Therefore, this paper attempts a short review on the numerical studies of CFS section with and without concrete under the flexural load. In particular, the CFS buckling failure modes were critically reviewed. Furthermore, the important considerations such as material properties definition and interactions during the numerical simulation were discussed. The review presented in this paper highlights considerable potential on how the nonlinearities of the concrete material, CFS-concrete interaction and connection types affect the level of simulation accuracy in predicting the flexural behavior of the composite beam. Moreover, the connections type, the nonlinear simulation methods and strategies and findings for the CFS-concrete flexural behavior were critically reviewed. The directions of the future research were provided through the concluded remarks and recommendations in achieving a higher accuracy of simulation results as well as more effective design philosophy in future to promote the utilization of CFS composite beam in construction industry.

“…1. The monotonic and cyclic performance of CFS bolted beam-to-column connections with through plates have been the topic of several investigations before [10][11][12][13][14][15][16]. The results of these studies, in general, show that CFS bolted moment connections follow a typical response comprising of a linear deformation phase followed by a slip range, a strength hardening response due to the bearing action of bolt shank against the steel sheet and finally a strength degradation phase caused by the local buckling of the connected CFS elements.…”
