However, BS 2853 has not been When looking at structural design for aluminium, Eurocode 9: Design of aluminium structures (often abbreviated as EN 1999 or EC 9) describes the principles and requirements for the proper design of aluminium alloy structures. Limit state design entails comparing factored design loads against reduced section and member capacities. 1 Welding errors 4-17 4. In addition, depending on the applied force, bolt compression and tension forces also can be calculated. E1 is fully restrained against lateral buckling throughout its span. the connections must have sufficient ductility to accommodate any inaccuracy in the design moment arising, for example, from frame Steel Design to Eurocode 3 EN 1993-1-8 Clause 2. The utilization against all the above checks is provided as a detailed calculation. Example of welded joint with a RHS column.
