C. COLD FORMED CROSS-SECTIONS

CHAPTER C: 'COLD ROLLING CROSS-SECTIONS' 3 1. METALLIC ELEMENTS OF COLD SPRING Cold-rolled elements are a group of metallic elements with the main characteristic of the production process as well as the small thickness. These characteristics dictate a number of differences from the process of analysis and dimensioning of hot-rolled metallic elements known to us so far. Numerous cross-sections can be found on the market, however the use of cold rolled members is generally limited due to the feeling that they are auxiliary elements. However, the reality is different as, in addition to tesserae/slugs, they may well be used as main load-bearing members. Due to the impossibility of lamination they are designed for practically elastic behaviour with corresponding seismic behaviour coefficients. In this version of SCADA PRO the cold rolled cross sections: • They are a different module from the other metallic sections • Can be used for all structural members (not just purlins/bevels) • Controlled under EC3-1-3 2. AVAILABLE CROSS-SECTIONS The cross-sections that can be used are of type C, S, Z and H (see picture). Cross section C Cross section S Cross section Z Cross section H The sections can be either unreinforced or have single or double end reinforcements (see picture below). The bending angle of the reinforcements and the cross-sectional beam Z is also parametrically defined. Note that this parametric property is not a user attribute but a feature of the code in the program. The user can only place ready-made profiles defined by the manufacturer (and us) and cannot modify them. The library includes sections of Greek and foreign companies.
