EN1999Eurocode 9: Design of aluminium structures

摘要: Eurocode 9 for the design of aluminium structures was a late addition to proposed suite European structural codes, reflecting relatively recent introduction alloys in construction industry as an alternative steel. With only third weight and self-protecting surface, material has clear advantages over steel but it also behaves very differently—with high buckling tendency, no yield plateau complex strain-hardening characteristics.The code, currently being converted EN standard, features several innovations including behavioural cross-section classes new calculation methods verification local buckling, evaluation rotation capacity connections.
