Linee guida per la progettazione strutturale di un concentratore solare

Abstract

La realizzazione di un qualsivoglia sistema solare a concentrazione, sia esso a torre o lineare parabolico od a disco, per una qualsiasi destinazione d’uso (produzione di energia elettrica, realizzazione di processi chimici, etc.) passa sempre attraverso la progettazione del campo solare e, più in particolare, del sistema di concentrazione. Il presente documento si pone l’obiettivo di fornire delle linee guida utili alla progettazione di un generico concentratore solare sulla base del suo inquadramento tipologico e della individuazione del quadro normativo da applicare nelle verifiche progettuali. L’insieme delle leggi, dei decreti, delle circolari e delle raccomandazioni che disciplinano, in Italia, la progettazione di strutture come quella in esame, permette di affrontare con sufficienti margini di sicurezza, le tematiche invariabilmente poste al progettista strutturale e riguardanti sia la funzionalità del concentratore che l’incolumità delle persone che vi operano. Il presente documento si pone l’obiettivo primario di adattare detta normativa al generico concentratore solare sviluppando quelle parti che sono più specifiche della struttura in oggetto come, ad esempio, i carichi ed in particolare le azioni dovute al vento ed alla neve. Per quanto riguarda i metodi di calcolo da adottare, si rinuncia ad utilizzare il metodo delle tensioni ammissibili ma, proiettandosi nel prossimo futuro, si dà indicazione sul modo di utilizzare il metodo degli Stati Limite.

The achievement of any concentrated solar power system, either tower or parabolic-trough or dish, for any use (electrical power production, chemical processes, etc.) goes always trough the design of the solar field and, in particular, of the concentration system. The objective of the present document is to supply the guidelines useful for the design of a generic solar concentrator on the base of its typological classification and of the selection of the norms to apply in the design verification. All the laws, the decrees, the circulars and the recommendations that discipline, in Italy, the design of structures like the one under investigation, allow to face with sufficient safety margins, the thematics invariably placed to the structural designer and regarding both the functionality of the concentrator and the security of the persons who operate on it. The main objective of the present work is to adapt the norm to the generic solar concentrator, developing the parts that are specific for the considered structure like, as an example, the loads and, in particular, the actions due to the wind and the snow. As far as the calculation methods to adopt, the method of the Permissible Stresses is rejected and indication on how to use the method of the Limit States is given.
