Els Codis tècnics de càlcul d'estructures metàl·liques a l'Estat espanyol al segle XX i el seu context històric Authors Josep M. Pons Poblet Lluís Torres Abstract The consequences associated to the potential accidents derived from collapse of structures or facilities throughout the time, have caused that the official organisms have developed specific codes to which the environment associated to that technology has had to adapt. Although it is evident that one of the fundamental purposes of these developed codes has been to guarantee the security of the people and the goods, we can not be conscious enough that usually they are bound to the socioeconomic environment and also to the historical context. In this article the case of the technical codes for structural design in Spain during XXth century will be exposed. Initially they were closely related to the railway industry, followed by the adaptation to the iron constraints at the conclusion of the Spanish Civil War and ending with the publication of Eurocodes, as a result of the European integration.
