Eurocode 9 - Design of aluminium structures - Part 1-1: General structural rules
EN 1999 applies to the design of buildings and civil engineering and structural works in aluminium. It complies with the principles and requirements for the safety and serviceability of structures, the basis of their design and verification that are given in EN 1990 - Basis of structural design. EN 1999 is only concerned with requirements for resistance, serviceability, durability and fire resistance of aluminium structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered. EN 1999 is intended to be used in conjunction with: - EN 1990 "Basis of structural design" - EN 1991 "Actions on structures" - European Standards for construction products relevant for aluminium structures - prEN 1090-1: Execution of steel structures and aluminium structures - Part 1: Requirements for conformity assessment of structural components5 - prEN 1090-3: Execution of steel structures and aluminium structures - Part 3: Technical requirements for aluminium structures5 EN 1999 is subdivided in five parts: EN 1999-1-1 Design of Aluminium Structures: General structural rules. EN 1999-1-2 Design of Aluminium Structures: Structural fire design. EN 1999-1-3 Design of Aluminium Structures: Structures susceptible to fatigue. EN 1999-1-4 Design of Aluminium Structures: Cold-formed structural sheeting. EN 1999-1-5 Design of Aluminium Structures: Shell structures.

Evrokod 9: Projektiranje konstrukcij iz aluminijevih zlitin - 1-1. del: Splošna pravila za konstrukcije
Standard EN 1999 se uporablja za projektiranje stavb ter inženirskih in konstrukcijskih objektov iz aluminija. Upošteva načela in zahteve glede varnosti in uporabnosti konstrukcij ter podlago za njihovo projektiranje in preverjanje, ki so podane v standardu EN 1990 – Osnove projektiranja. Standard EN 1999 se nanaša le na zahteve za odpornost, uporabnost, trajnost in požarno odpornost aluminijastih konstrukcij. Ostale zahteve, na primer glede toplotne in zvočne izolativnosti, niso obravnavane. Standard EN 1999 je namenjen za uporabo v povezavi z naslednjimi standardi: – EN 1990 »Osnove projektiranja« – EN 1991 »Vplivi na konstrukcije« – Evropski standardi za konstrukcijske izdelke v zvezi z aluminijastimi konstrukcijami – prEN 1090-1: Izvedba jeklenih konstrukcij in aluminijastih konstrukcij – 1. del: Zahteve za ugotavljanje skladnosti sestavnih delov konstrukcij5 – prEN 1090-3: Izvedba jeklenih konstrukcij in aluminijastih konstrukcij – 3. del: Tehnične zahteve za aluminijaste konstrukcije5 EN 1999 je razdeljen na pet delov: EN 1999-1-1 Projektiranje konstrukcij iz aluminijevih zlitin: Splošna pravila za konstrukcije.
