Literature Review on Cold-Formed Steel Lipped Channel Beams About Shear Behaviour

Cold-formed steels (CFS) or light gauge steels (LGS) are steel sections created through processes without heat application, such as roll forming or press-braking. In the past few decades, the utilization of CFS as a structural material has expanded due to its advantages over the other materials used in the construction industry, consequently increasing the number of studies conducted by many researchers. CFS studies have focused on many research areas, including designing and analyzing members and systems, connections, sustainability, residual stresses and post-fire data. Cold-formed high strength steel members are increasingly used as primary load bearing components in low-rise buildings. Lipped channel beam (LCB) is one of the most commonly used flexural members. International design codes – European standards (EN1993-1-3), North American standards (AISI S100) and Australian and New-Zealand standards (AS/NZS 4600) – contain shear design provisions to estimate the shear strength of CFS sections. The literatures were collected based on the previous investigations in the field of shear behaviour and design of ultra-high strength cold-formed steel lipped channel beams.
