EN 1999 Eurocode 9 applies to the design of buildings and other 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 concerned with requirements for resistance, serviceability, durability and fire resistance of aluminium structures.
