“…Conversely, the flexural strength predictions generated by DSM in the AISI S100 for unstiffened zed section members were generally conservative, whereas the design for edge-stiffened Z-section beams was marginally less so [105]. Furthermore, DSM can be employed to compute the ultimate load-bearing capability of lipped channels incorporating edge stiffeners of varying complexities undergoing D-G interactions [106]. To enhance flexural strength, intermediate stiffeners are to be utilized with or without an edge stiffener for closed built-up CFS sections and for the flange or web of open built-up CFS [107].…”

“…By providing out-of-plane support, the stiffeners positioned midway along the slit length may reduce the links' susceptibility to torsional buckling [108]. Notably, the intricacy of the edge stiffener is less important than the form of the stiffener (inward or outward) when it comes to buckling strengths [106].…”

The utilization of cold-formed steel (CFS) sections in construction has become widespread due to their favorable attributes, including their lightweight properties, high strength, recyclability, and ease of assembly. To ensure their continued safe and efficient utilization, this review provides a comprehensive investigation into the factors influencing the strength of CFS members. This analysis encompasses design codes, prediction methodologies, material properties, and various structural configurations. This review uncovers discrepancies among existing design codes, particularly noting conservative predictions in AISI and AS/NZS standards for composite and built-up sections. Additionally, the effectiveness of prediction methods such as the direct strength method and effective width method varies based on specific structural configurations and loading conditions. Furthermore, this review delves into recent advancements aimed at enhancing fire resistance, connection design, and the composite behavior of CFS structures. The influence of factors such as eccentricity, sheathing materials, and bolt spacing on structural performance is also examined. This study underscores the crucial role of accurate prediction methods and robust design standards in ensuring the structural integrity and safety of CFS constructions. Through a comparative analysis, it is revealed that AISI and AS/NZS standards exhibit conservatism in predicting nominal buckling loads compared to experimental data. Conversely, a non-linear finite element analysis demonstrates a strong correlation with laboratory tests, offering a more accurate prediction of nominal buckling capacity. Overall, this review offers comprehensive insights aimed at optimizing CFS structural design practices. By identifying key areas for future research and development, this work contributes to the ongoing advancement of safe and efficient CFS construction applications.
