Evrokod 9 - Projektiranje konstrukcij iz aluminijevih zlitin - 1-1. del: Splošna pravila
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 konstrukcij.
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 gradbene izdelke, ki se nanašajo na aluminijaste konstrukcije
– EN 1090-1: Izvedba jeklenih in aluminijastih konstrukcij – 1. del: Zahteve za ugotavljanje skladnosti sestavnih delov konstrukcij
– EN 1090-3: Izvedba jeklenih in aluminijastih konstrukcij – 3. del: Tehnične zahteve za aluminijaste konstrukcije.
Standard EN 1999-1-1 določa osnovna pravila za projektiranje konstrukcij iz gnetenih aluminijevih zlitin in podaja omejene smernice za ulite zlitine.
Če ni v tem standardu izrecno navedeno drugače, se priporočajo naslednje omejitve:
sestavni deli naj imajo debelino materiala vsaj 0,6 mm;
varjeni sestavni deli naj imajo debelino materiala vsaj 1,5 mm;
za povezave naj se uporabljajo:
– jekleni sorniki in zatiči s premerom vsaj 5 mm;
– aluminijasti sorniki in zatiči s premerom vsaj 8 mm;
– zakovice in samorezni vijaki s premerom vsaj 3,9 mm.
