(1) EN 1999-1-1 gives basic design rules for structures made of wrought aluminium alloys and limited guidance for cast alloys (see section 3).NOTE Minimum material thickness may be defined in the National Annex. The following limits are recommended ? if not otherwise explicitly stated in this standard:- components with material thickness not less than 0,6 mm;- welded components with material thickness not less than 1,5 mm;- connections with:o steel bolts and pins with diameter not less than 5 mm;o aluminium bolts and pins with diameter not less than 8 mm;o rivets and thread forming screws with diameter not less than 4,2 mm (2) The following subjects are dealt with in EN 1999-1-1:Section 1: GeneralSection 2: Basis of designSection 3: MaterialsSection 4: DurabilitySection 5: Structural analysisSection 6: Ultimate limit states for membersSection 7: Serviceability limit statesSection 8: Design of jointsAnnex A Execution classes Annex B Equivalent T-stub in tension Annex C Materials selectionAnnex D Corrosion and surface protectionAnnex E Analytical models for stress strain relationshipAnnex F Behaviour of cross section beyond elastic limitAnnex G Rotation capacityAnnex H Plastic hinge method for continuous beamsAnnex I Lateral torsional buckling of beams and torsional or flexural-torsional buckling of compression membersAnnex J Properties of cross sectionsAnnex K Shear lag effects in member designAnnex L Classification of connectionsAnnex M Adhesive bonded connections (3) Sections 1 to 2 provide additional clauses to those given in EN 1990 ?Basis of structural design?. (4) Section 3 deals with material properties of products made of structural aluminium alloys. (5) Section 4 gives general rules for durability. (6) Section 5 refers to the structural analysis of structures, in which the members can be modelled with sufficient accuracy as line elements for global analysis. (7) Section 6 g
The document gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of package skid-mounted, reciprocating, separable or integral compressors with lubricated cylinders and their prime movers, for use in the petroleum and natural gas industries for the compression of hydrocarbon gas.#,,#
