dc.description.abstractCold-formed steel (CFS) members are extensively used in construction industry as the primary and/or secondary load-bearing structural systems. CFS products can be mass manufactured at room temperature and rapidly installed on-site. Compared to the traditional hot-rolled steel and concrete structures, CFS structures have a high capacity-to-weight ratio and present real benefits and opportunities for architects and engineers to achieve a greener structural solution. CFS products are typically formed by bending steel sheets or strips (up to 6 mm thick) using a number of rollers (roll-forming) or die blocks (brake-pressing). The current manufacturing process allows the CFS products to be shaped into any desired (infinite) cross-sectional shapes with consecutive manufacturing bends. However, most of the commonly used CFS cross-sectional shapes are mainly restricted to “Cee”, “Zee” and “Sigma”. To address the issue of local instabilities, the conventional cross-sections have been improved by the inclusion of web and/or flange stiffeners and the optimisation of their dimensions (height, width and thickness). Despite these advances in cross-sectional design, little research has been done to discover new cross-sectional shapes to achieve an optimum solution. A revolutionary innovation in the crosssectional shape of the CFS products is therefore being pushed forward in this research.en_US
