BS EN 1996-3:2006 pdf download.Eurocode 6— Design of masonry structures — Part 3: Simplified calculation methods for unreinforced masonry structures.
(l)P The scope of Eurocode 6 for Masonry Structures as given in 1.1.1 of EN 1996-1-1:2005 applies also to this EN 1996-3.
NOTE: Ewocodc 6 deals only with the requirements for resistance. scriceabiliIy and duxabil.Iy of structures. Other requirements are not condeie& Euroccidc 6 does not cover the special requirements of seismic design.
(2)P EN 1996.3 provides simpliticd calculation methods to facilitate the design of the following unreinfiwced masonry walls, subject to certain conditions of application:
walls subjected to vertical loading and wind loading; walls subjected to concentrated loads:
shear walls;
— basement walls subjected to lateral earth pressure and vertical loatLs; walls subjected to lateral loads but not subjected to vertical loads.
(3)P The rules given in EN 1996-3 are consistent with those given in EN 1996-I-I, but are more conservative in respect of the conditions and limitations of their use.
(4) For those types of masonry structure or parts of structures not covered by (1), the design shall be based on EN 1996-I-i.
(5) This EN 1996-3 applies only to those masonry structures, or parts thereof, that are described in EN 1996- I-I and EN 1996-2.
(6) The simplified calculation methods given in this EN 1996-3 do not cover the design for accidental situations.
1.2 Normative references
(l)P The references in 1.2 ofEN 1996-1-1:2005 apply to this EN 1996-3.
1.3 Assumptions
(l)P The assumptions given in 1.3 of EN l9902002 apply to this EN 1996-3.
1.4 Distinction behseen Principles and Application Rules
(I )P The rules of 1.4 of EN 1990:2002 apply to this EN 1996-3.
2 Basis of design
2.1 General
(I )P The design of masonly buildings shall he in accordance with the general rules given in EN
1990.
(2)P Specitic provisions for masonry structures are given in section 2 of EN 1996-1-1:2005 and
shall be applied.
2.2 Basic variables
(l)P Actions shall be obtained from the relevant parts of EN 1991.
(2)P Partial factors for load shall be obtained from EN 1990.
(3)P Properties for materials and construction products and geometrical data to be used for design shall be those specilied in EN 1996-I-I, or other relevant hENs of ETAs. unless otherwise indicated in this EN 1996-3.
2.3 Verification by (he partial factor method
(I )P The verification by the partial factor method shall be done according to clause 2.4 of EN
1996-1-1:2005.
NOTE: Thc notes 102.4.2 of EN 1996-1-1:2005 also apply.
(2)P The relevant values of the partial factor for materials shall be used for the ultimate limit state for ordinary situations.
NOTE: The numencal values to be ascnbed to the symbol may be found in the National Annex. Recommended a1ucs arc those as gicn in clause 2.4.3 of EN 1996-1-1:2005. Thc recommended valucs for maaonry arc repeated in the table below.
3 Niaterials
3.1 General
(I)P The materials uscd in the masonry walls rctcrrcd to in this EN 1996-3 shall be in accordance with Section) of EN 1996-1-1:2005.
(2) Masonry units should be grouped as Group I. Group 2. Group 3 or Group 4 according to clause
3.1.1 ofEN 1996-1.1:2005.
NOTE: Ncwrnally the manufacwrer will Uuc the grouping of his units in his product declaration.
3.2 CharacteristIc compressive strength of masonry
(I )Thc characteristic comprcssivc strength of masonry should be determined according to 3.6.1 of EN 1996-I-i :2005.
(2) A simplified method to determine the char4cteristic compressive strength of masonry ftir use in this document is provided in Annex D.
3.3 Characteristic flexural strength of masonry
(I) The characteristic flexural strength of masonry should be determined according to 3.6.3 of
EN 1996-1-1:2005.
(2) A simplified method to determine the characteristic flexural strengths of masonry for use in this document is provided in Annex D.
3.4 Characteristic initial shear strength of masonry
(I) The characteristic initial shear strength of inasorny. J,. should be determined according to
3.6.2 of EN 1996-1-1:2005.
