12、ent to NCI re Annex A Replace NCI to Annex A as follows: The informative Annex A is adopted as a normative Annex, with the exception of A.3. A.3 does not apply in Germany. The coefficient cA= 0,4 shall be used for walls with a slenderness ratio hef/t 18 and a characteristic compressive strength of t

13、he masonry of fk5,5 m. When applying DIN EN 1996-3:2010-12, Annex A.2 (1), for walls with a slenderness ratio of 18 hef/t 21, and for walls in general that are used as end supports in the uppermost storey, particularly below roof decks, the bearing capacity factor cAin Equation (A.1) shall always be

14、 cA= 0,33 In the case of floors supported over part of the width of the wall, when using the verification method according to DIN EN 1996-3:2010-12, Annex A, the wall thickness t shall be at least 36,5 cm. DIN EN 1996-3/NA/A2:2015-01 5 5 Amendment to NCI re Annex C Add the following paragraph after paragraph 1: Application of this annex to determine the largest permissible areas of high precision masonry is only permitted if the overlap is 0,4 hu.
