Building Regulations 2015​

Building work in new and altered buildings in Denmark

The Building Regulations contain the Danish rules for building work in new buildings, extensions, conversions and other rebuilding work, as well as changes in the use of buildings that are important in relation to the Danish Building Act or the Building Regulations, the demolition of buildings and alterations and other rebuilding work that may affect the consumption of energy in the building. The Building Regulations apply to building work carried out in the Danish market.

Their primary field of application is multi-storey buildings for residential purposes and all kinds of commercial, industrial and institutional buildings, including the categories listed in section 11 of the Danish Building Act, single-family houses for permanent residence, either as detached single-family houses or linked single-family houses, holiday homes in summer house areas, allotment sheds, campsite cabins and garages, outbuildings, and other secondary buildings.

(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: General
Section 2: Basis of design
Section 3: Materials
Section 4: Durability
Section 5: Structural analysis
Section 6: Ultimate limit states for members
Section 7: Serviceability limit states
Section 8: Design of joints
Annex A Execution classes
Annex B Equivalent T-stub in tension
Annex C Materials selection
Annex D Corrosion and surface protection
Annex E Analytical models for stress strain relationship
Annex F Behaviour of cross section beyond elastic limit
Annex G Rotation capacity
Annex H Plastic hinge method for continuous beams
Annex I Lateral torsional buckling of beams and torsional or flexural-torsional buckling of compression members
Annex J Properties of cross sections
Annex K Shear lag effects in member design
Annex L Classification of connections
Annex 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
