Review: development of performance-based fire design for cold-formed steel
Performance-based fire design for cold-formed steel systems is in its infancy. This paper brings together existing research on cold-formed steel materials, members, and assemblages at elevated temperatures; and complementary analysis and design methods necessary for the development of analysis-based design for cold-formed steel systems under fire. Cold-formed steel systems have become popular i...
متن کاملReview on Cold-Formed Steel Connections
The 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...
متن کاملOn Cold-Formed Steel Construction
Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...
متن کاملComputational Modeling of Cold-formed Steel
The objective of this paper is to summarize recent research and experiences with computational modeling of cold-formed steel conducted within the author’s research group at Johns Hopkins University. This admittedly biased view of computational modeling focuses primarily on the use of the semi-analytical finite strip method and collapse modeling using shell finite elements. Issues addressed incl...
متن کاملCold-formed steel structures around the world
Today, cold-formed steel (CFS) structures enjoy widespread use in many countries and design specifications, e.g., [1] and [2] are well established, even if they are ever changing! Extensive reviews of the CFS literature are available [3], [4] and more targeted research reviews also exist: [5], [6] and Chapter 13 of [7]. However, even in the last five years significant progress has been made, pa...
