Design of Cold-formed Steel Structures

Dan Dubina is professor and head of the Department of Steel Structures and Structural Mechanics at the Politehnica University of Timisoara, Romania. He has published more than 400 scientific papers and 25 books in the field of cold-formed steel structures, steel structures in seismic areas, structural connections, and structural analysis. He is a member of the ECCS Technical Committees TC 7 (Cold Formed Thin Walled Sheet Steel in Building), TC 8 (Stability), TC 10 (Connections), and TC 13 (Seismic Design). He has been awarded with the ECCS European Steel Design Award twice. Raffaele Landolfo is professor of structural engineering at the University of Naples "Federico II". He is external examiner for MSc in earthquake engineering and structural steel design at the Imperial College London and he also teaches in several PhD and master courses. He is head of the Department of Constructions and Mathematical Methods in architecture at the University of Naples. He was engaged in the activities of both national working groups and European project teams dealing with the conversion from ENV to EN of the EN 1993-1-3, and he is chairing the ECCS Technical Committee TC 13 (Seismic Design). Viorel Ungureanu is associate professor at the Politehnica University of Timisoara, Romania. His research is focused on the field of steel structures and especially cold-formed thin-walled structures. He contributed to the translation of EN 1993-1-3 into Romanian and was part of the team which elaborated the Romanian National Annexes for this document. He is a member of the ECCS TC 7 (Cold Formed Thin Walled Sheet Steel in Building).

“The authors are clearly extremely experienced in the structural design and behaviour of cold-formed steel and they are also deeply knowledgeable about the content of EN 1993-1-3. The credentials of the authors and fact that the book forms part of the ECCS series of Eurocode Design Manuals means that this will become an authoritative text for engineers with an interest in the design of cold-formed steel.”  (The Structural Engineer, 1 July 2013
