By looking at the past and present role of thin structures in the history of reinforced concrete, a clear line of its development can be seen. This line of development has not yet been fully explored. This paper will show the main steps of this evolution from the first patents of the 2nd half of the 19th century to the latest applications. The presentation will begin with the first French patents where the reinforced concrete was a thin plate with a simples teel mash inside and it will continue by showing the bif German domes only 60 mm thick built between 1920 and 1930, the invention of “Ferro-cemento” by Pier Luigi Nervi in 1945 and his famous applications in the construction of the large coverings of exhibition and sport halls in 1960. As for the present the paper will illustrate the new technologies of thin bearings walls wish spatial steel frame and support insulation.
