Il testo ripropone una lettura dei dati di out-put della ricerca Le leghe metalliche per i sistemi di involucro a cui l'autore ha partecipato all’interno dell’Unità Operativa di Ricerca dell’Università Mediterranea di Reggo Calabria. – sede di Coordinamento Nazionale del Programma di Ricerca Cofinanziato PRIN 2005/2007, dal titolo Percorsi e gestione delle informazioni tecniche per la promozione ed il controllo dell’innovazione nei materiali e nel Progetto di Architettura. La Ricerca, partendo da un esplicito interesse per le leghe metalliche, esplora il tema dell’alluminio per usi strutturali, un campo d’applicazione caratterizzato da forte sperimentalità, da problematiche operative ancora irrisolte e, soprattutto, da conoscenze specialistiche poco diffuse. Sono molteplici le questioni indagate che attengono allo sfruttamento completo delle peculiarità offerte dal materiale e all'accettazione di ciò che, invece, attualmente, rappresenta il portato oggettivo dei suoi limiti. Le tematiche trattate riguardano aspetti informativi definitori e aspetti informativi specialistici. Gli aspetti definitori esprimono informazioni sulla storia del materiale, sulla produzione, sulla normativa specifica e sulle bibliografie di riferimento. Ad esse si aggiungono informazioni di base: - caratteristiche tecniche (leggerezza, resistenza meccanica, plasticità̀, formabilità, resistenza agli agenti atmosferici e attitudine ai trattamenti superficiali); - tecniche di produzione (laminazione, estrusione, processi di fonderia, forgiatura); - applicazioni possibili e modellazioni auspicabili nella direzione degli impieghi propriamente strutturali e con riferimento all'elevato rapporto resistenza/peso; - aspetti tecnico-progettuali. Le informazioni specialistiche riguardano, invece, dati e condizioni d’uso particolarmente utili per il progetto, ai quali si è pervenuti attraverso l’analisi valutativa di casi studio, volti a sottolineare i caratteri connotanti l'innovazione del materiale e le sintesi informative in relazione alle diverse problematiche progettuali. In particolare, sono affrontate le questioni che attengono all’uso strutturale del materiale in architettura ai fini di una loro divulgazione, con riferimento ai diversi tipi attualmente impiegati: telai, sistemi reticolari, pannelli, strutture per involucri e facciate continue. Vengono, infine, analizzate ed esplicitate, in termini valutativi, informative particolari dei caratteri del materiale, in relazione alle specifiche ricadute sulle azioni del progetto e al suo controllo qualitativo: trasferimento delle informazioni alla fase di realizzazione, convenzioni grafiche, problemi di pre-dimensionamento, performance nel tempo, perfomance ambientali, performance economiche.
