11、tee). This document is the National Annex to DIN EN 1996-2:2010-12, Eurocode 6: Design of masonry structures Part 2: Design considerations, selection of materials and execution of masonry. European Standard EN 1996-2:2006 allows national safety parameters, referred to as Nationally Determined Parame

12、ters (NDPs), to be specified for a number of points. The NDPs cover alternative verification methods, the provision of individual values and the selection of classes from designated classification systems. The relevant parts of the text are identified in the European Standard by references to the po

13、ssibility of national choice and are listed in Clause NA.2.1. This National Annex also includes non-contradictory complementary information (NCI) for the application of DIN EN 1996-2:2010-12 National paragraphs are preceded by the letters NA and the paragraph number in brackets. This National Annex

14、is an integral part of DIN EN 1996-2:2010-12. Amendments This document differs from DIN 1053-1:1996-11 and DIN 1053-3:1990-02 as follows: a) a number of provisions from the above standards have been included in this National Annex as non-contradictory complementary information (NCI); b) nationally d

15、etermined parameters (NDPs) have been included in accordance with EN 1996-2; c) provisions for basement walls and for cavity walls are given in separate annexes.

27、I re 2.2.1 General (NA.4) In order to simplify execution and inspection, the number of different types of masonry unit and mortar groups used in any single storey should be limited. (NA.5) Masonry units and mortars that remain directly exposed to outdoor conditions shall be frost-resistant. If the p

28、roduct standard includes a number of frost resistance classes, the units with the highest frost resistance shall be used for chimney coping, basement entrances, retaining walls, garden walls, textured masonry walls and similar applications. Calcium silicate masonry units with surface coatings may on

29、ly be used in outer leaves if their frost resistance under unfavourable weather conditions has been verified in accordance with DIN EN 771-2 or DIN V 106. NCI re 2.2.4 Ancillary components and reinforcement (NA.2) Note 1 and Annex C do not apply in Germany. NDP re 2.3.1 Detailing Annexes NA.D and NA

30、.E contain additional information. NCI re 2.3.1 Detailing (NA.2) Horizontal and gently sloping masonry surfaces that are directly exposed to outdoor conditions such as wall copings, chimney copings or parapets shall be designed so as to prevent ingress of water (e.g. by providing coverings or drip e

31、dges). DIN EN 1996-2/NA:2012-01 6 NCI re 2.3.2 Joint finishes (NA.2) Joints in vaulting masonry shall be as narrow as possible, with a thickness not exceeding 20 mm at the extrados. Outer walls shall be designed to withstand driving rain. Reference should be made to the guidance given in DIN 4108-3.

32、 NDP re 2.3.4.2(2) Spacing of movement joints The values recommended in Note 1 apply. Re 3 Execution NCI re 3.1 General (NA.3) Annex NA.F contains guidance on checking and testing masonry units and mortar. NDP re 3.4(3) Permissible deviations The provisions regarding the permissible deviations of ma

33、sonry elements given in Table 3.1 apply. They do not affect more detailed provisions, such as those given in DIN 18202. NDP re 3.5.3.1(1) Pointing The minimum depth of joints to be pointed is given in NA.D.1, paragraph (4), d). NCI re 3.6.3 Protection against freeze/thaw cycling (NA.3) When building

34、 in cold weather where there is a risk of frost, all materials and walls shall be properly protected against freezing (e.g. by enclosing them). (NA.4) The use of anti-freezing agents is not permitted. Freshly laid masonry shall be protected against frost, e.g. by covering. (NA.5) The use of de-icing

35、 salt is not permitted. (NA.6) Any parts of masonry walls damaged by frost or other effects shall be removed before continuing the work. NCI re Annex B Acceptable specifications of masonry units and mortar for durable masonry in various exposure conditions Annex B does not apply in Germany. NCI re A

36、nnex C Selection of material and corrosion protection specifications for ancillary components according to exposure classes Annex C does not apply in Germany. DIN EN 1996-2/NA:2012-01 7 NCI Annex NA.D (informative) Cavity walls NOTE Provisions from various parts of DIN EN 1996 have been grouped toge

37、ther in this Annex in order to provide an overview. This Annex does not contain any new provisions. NA.D.1 General provisions with regard to execution (1) The space between the two masonry leaves of a cavity wall generally a loadbearing inner leaf and a non-loadbearing outer leaf is referred to as a

38、 cavity. The cavity may or may not contain thermal insulation. (2) Cavity walls may be designed as uninsulated walls, i.e. the space between the two leaves does not contain any thermal insulation. The width of the cavity thus corresponds to the distance between the two masonry leaves. (3) Cavity wal

39、ls may also be either partially or fully filled with thermal insulation material. In this case, the thermal insulation may consist of either a single layer or several layers of thermal insulating material. (4) The following applies to non-loadbearing outer leaves (i.e. veneer walls or facework) tied

40、 to a loadbearing backing wall (inner leaf): a) The design shall be based on the thickness of the loadbearing inner leaf only. b) The minimum thickness of outer leaves is 90 mm. Thinner outer leaves are treated as cladding as specified in DIN 18515. The minimum length of any masonry piers in the out

41、er leaf that only have to withstand loads from the outer leaf shall be 240 mm. The outer leaf should be supported over its entire length and width. Where the support is interrupted (e.g. by corbels) all masonry units shall be supported on both sides. c) The outer masonry leaf shall be made of frost-

42、resistant masonry units or rendered non-frost resistant masonry units. The rendering shall satisfy the requirements of DIN EN 998-1 in conjunction with DIN V 18550. d) Outer leaves with thicknesses of 115 mm should be laterally supported at vertical intervals of around 12 m. They may extend up to 25

43、 mm beyond their support. If such leaves do not extend over more than two storeys or they are supported at every second storey they may project beyond the support by up to 38 mm. Allowance for such projections shall be made in the analysis of the bearing pressure. Where exposed joints are not finish

44、ed flush, they should be raked out to a depth of at least 15 mm and then pointed. e) Outer leaves with thicknesses t equal to or greater than 105 mm and less than 115 mm are not permitted to exceed a height of 25 m above ground level and shall be laterally supported at vertical intervals of around 6

45、 m. Gables not exceeding 4 m in height in buildings up to two full storeys high do not need any additional lateral support. Such outer leaves shall not extend more than 15 mm beyond their supports and the mortar joints should be finished flush. Where exposed joints are not finished flush, they shoul

46、d be raked out to a depth of at least 15 mm and then pointed. DIN EN 1996-2/NA:2012-01 8 f) Outer leaves with thicknesses t equal to or greater than 90 mm and less than 105 mm are not permitted to exceed a height of 20 m above ground level and shall be laterally supported at vertical intervals of ar

47、ound 6 m. Gables not exceeding 4 m in height in buildings up to two full storeys high do not need any additional lateral support. Exposed joints should be finished flush. Such outer leaves shall not extend more than 15 mm beyond their supports. g) The masonry leaves shall be connected by stainless s

48、teel ties with a German national technical approval (agrment) or by stainless steel ties in accordance with DIN EN 845-1 whose application is covered by a German national technical approval. The following applies to ties with the shapes and dimensions shown in Figure NA.D.1: vertical spacing: not more than 500 mm; horizontal spacing: not more than 750 mm; clear distance between the masonry leaves: not more than 150 mm; diameter: 4 mm; general purpose masonry mortar of group IIa or better;
