Cold formed steel Wikipedia. Cold formed steel CFS is the common term for products made by rolling or pressing steel into semi finished or finished goods at relatively low temperatures cold working. Cold formed steel goods are created by the working of steel billet, bar, or sheet using stamping, rolling including roll forming, or presses to deform it into a usable product.

Cold worked steel products, such as cold rolled steel CRS bar stock and sheet, are commonly used in all areas of manufacturing of durable goods, such as appliances or automobiles, but the phrase cold formed steel is most prevalently used to describe construction materials. The use of cold formed steel construction materials has become more and more popular since its initial introduction of codified standards in 1. In the construction industry both structural and non structural elements are created from thin gauges of sheet steel. These building materials encompass columns, beams, joists, studs, floor decking, built up sections and other components. Cold formed steel construction materials differ from other steel construction materials known as hot rolled steel see structural steel. The manufacturing of cold formed steel products occurs at room temperature using rolling or pressing. The strength of elements used for design is usually governed by buckling. The construction practices are more similar to timber framing using screws to assemble stud frames. Cold formed steel building. Cold formed steel members have been used in buildings, bridges, storage racks, grain bins, car bodies, railway coaches, highway products, transmission towers, transmission poles, drainage facilities, various types of equipment and others. These types of sections are cold formed from steel sheet, strip, plate, or flat bar in roll forming machines, by press brake machine press or bending operations. The material thicknesses for such thin walled steel members usually range from 0. Steel plates and bars as thick as 1 in. AISI, 2. 00. 7b. 2HistoryeditThe use of cold formed steel members in building construction began in the 1. United States and Great Britain. In the 1. 92. 0s and 1. One of the first documented uses of cold formed steel as a building material is the Virginia Baptist Hospital,3 constructed around 1. Lynchburg, Virginia. The walls were load bearing masonry, but the floor system was framed with double back to back cold formed steel lipped channels. According to Chuck Greene, P. E of Nolen Frisa Associates,4 the joists were adequate to carry the initial loads and spans, based on current analysis techniques. Greene engineered a recent renovation to the structure and said that for the most part, the joists are still performing well. A site observation during this renovation confirmed that these joists from the roaring twenties are still supporting loads, over 8. In the 1. 94. 0s, Lustron Homes built and sold almost 2. History of AISI design standardseditDesign standards for hot rolled steel see structural steel were adopted in 1. Cold formed steel members maintain a constant thickness around their cross section, whereas hot rolled shapes typically exhibit tapering or fillets. Cold formed steel allowed for shapes which differed greatly from the classical hot rolled shapes. The material was easily workable it could be deformed into many possible shapes. Even a small change in the geometry created significant changes in the strength characteristics of the section. It was necessary to establish some minimum requirements and laws to control the buckling and strength characteristics. Also it was observed that the thin walls underwent local buckling under small loads in some sections and that these elements were then capable of carrying higher loads even after local buckling of the members. In the United States, the first edition of the Specification for the Design of Light Gage Steel Structural Members was published by the American Iron and Steel Institute AISI in 1. AISI, 1. 94. 6. 5 The first Allowable Stress Design ASD Specification was based on the research work sponsored by AISI at Cornell University under the direction of late Professor George Winter 2 since 1. As a result of this work, George Winter is now considered the grandfather of cold formed steel design. The ASD Specification was subsequently revised in 1. Cornell and other universities Yu et al., 1. In 1. 99. 1, AISI published the first edition of the Load and Resistance Factor Design Specification developed at University of Missouri of Rolla and Washington University under the directions of Wei Wen Yu 3 and Theodore V. Galambos AISI, 1. Both ASD and LRFD Specifications were combined into a single specification in 1. AISI, 1. 99. 6. 9In 2. North American Specification for the Design of Cold Formed Steel Structural Members was developed by a joint effort of the AISI Committee on Specifications, the Canadian Standards Association CSA Technical Committee on Cold Formed Steel Structural Members, and Camara Nacional de la Industria del Hierro y del Acero CANACERO in Mexico AISI, 2. It included the ASD and LRFD methods for the United States and Mexico together with the Limit States Design LSD method for Canada. This North American Specification has been accredited by the American National Standard Institute ANSI as an ANSI Standard to supersede the 1. AISI Specification and the 1. CSA Standard. Following the successful use of the 2. Wynton Marsalis Transcriptions Pdf. North American Specification for six years, it was revised and expanded in 2. This updated specification includes new and revised design provisions with the additions of the Direct Strength Method in Appendix 1 and the Second Order Analysis of structural systems in Appendix 2. In addition to the AISI specifications, the American Iron and Steel Institute has also published commentaries on various editions of the specifications, design manuals, framing design standards, various design guides, and design aids for using cold formed steel. For details, see AISI 4 website. International codes and standardseditThe United States, Mexico and Canada use the North American Specification for the Design of Cold Formed Steel Structural Members, document number AISI S1. Member states of the European Union use section 1 3 of the Eurocode 3 EN 1. Other nations utilize various design specifications, many based on AISI S 1.
