AbstractIntroductionResearches on Cold-Formed Steel ConnectionsDiscussionConclusionAcknowledgmentsThe concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the thin-walled behaviour.
