Abstract

The first steel spatial structure for a roof dated in Spain was erected in 1952. From this pio-neer experience authored by Eduardo Torroja and Florencio del Pozo, a series of other interest-ing realizations were followed by different architects and engineers. A special characteristic of all these early experiences was the limited availability of bars and manufactured elements spe-cific for the special complexity of this kind of structures. For example, it was not until 1962 that steel tubes could be used in a spatial truss in Spain. Before that, ingenious solutions with stan-dard rolling profile elements were employed. In spite of these difficulties, from the beginning of the 60s, simple ways of union between bars were developed and the first important structures of this type were assembled in Spain. Af-ter several previous experiences, at the end of the decade, engineers Bueno y Calavera designed and constructed a roof for a sport arena in Madrid covering a rectangle of 70 x 50 m. The joints of the structural elements were always welded and an extensive use of skilful labor was needed. Only some years later but already in the early 70s, the engineers Calavera and González Valle built the most important spatial truss of this early period: the roof for the National Cattle Market in Torrelavega (Cantabria). The solution there was a low rise vault measuring 250 x 60 m. The aim of this paper is to describe and analyze the particular systems used in Spain these first years, a period leading to the outbreak of international patents later widely used as Mero and others. The Spanish experiences shall be exemplified by their most outstanding achievements, but also by other minor but interesting examples of a more peculiar character. Among them de-serves mention the removable system developed by the designer Carrillo Figueras and used for the Spanish Pavilion of the Teheran 1969 exhibition. For all of them it was not only important the structural design but also the methods of on site assembly.
