Eurocode 6: Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures

(1)P The basis for the design of buildings and civil engineering works in masonry is given in this Part 1-1 of Eurocode 6, which deals with unreinforced masonry and reinforced masonry where the reinforcement is added to provide ductility, strength or improve serviceability. The principles of the design of prestressed masonry and confined masonry are given, but application rules are not provided. This Part is not valid for masonry with a plan area of less than 0,04 m2.
(2) For those types of structures not covered entirely, for new structural uses for established materials, for new materials, or where actions and other influences outside normal experience have to be resisted, the principles and application rules given in this EN may be applicable, but may need to be supplemented.
(3) Part 1-1 gives detailed rules which are mainly applicable to ordinary buildings. The applicability of these rules may be limited, for practical reasons or due to simplifications; any limits of applicability are given in the text where necessary.

Overview

SIST EN 1996-1-1:2006/kprA1:2012 is an amendment to the Eurocode 6 standard focused on the design of masonry structures. This part of Eurocode 6, titled "Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures," serves as the fundamental basis for designing ordinary masonry buildings and civil engineering works. It comprehensively addresses both unreinforced masonry and reinforced masonry where reinforcement enhances structural ductility, strength, or serviceability.

The standard also outlines principles applicable to prestressed and confined masonry, although detailed application rules for these are not included. EN 1996-1-1 specifically excludes masonry with a plan area less than 0.04 m² from its scope. While this standard primarily targets conventional buildings, it provides adaptable guidelines for new structural uses, novel materials, or unusual loading conditions requiring resistance beyond typical experience.

Key Topics

• Composite Lintels
  The amendment introduces definitions and design rules for composite lintels made of prefabricated parts combined with complementary in-situ masonry elements. The standard specifies:

  • Built-in length declared by the manufacturer (per EN 845-2)
  • Load transfer and shear strength at the interface of prefabricated parts and masonry
  • Calculation and verification methods for bending moments, shear stresses, and vertical load resistance
  • Guidelines for considering composite lintels as simply supported or deep beams depending on geometry and load conditions

• Shear and Tensile Strength Parameters
  The characteristic shear strength of interfaces and the tensile strength of prefabricated lintel parts must be declared by manufacturers and factored into design calculations with appropriate partial safety factors.

• Structural Verification Procedures
  Updated clauses provide detailed methods to verify composite lintels under vertical and shear loadings, including limiting design equations and recommendations on material properties following European standards.

• Material and Design Assumptions
  The amendment emphasizes using material properties defined in harmonized European standards, facilitating harmonization and reliability in design practice across Europe.

Applications

• Design of Ordinary and Reinforced Masonry Structures
  The standard applies to the structural design of masonry buildings and civil structures including walls, partitions, and load-bearing members where reinforcement is used for strength improvement or ductility.

• Composite Lintel Engineering
  Engineers designing composite lintels that combine prefabricated concrete or masonry parts with cast-in-place masonry elements will benefit from the newly introduced design principles, improving safety, efficiency, and constructability.

• Retrofit and Rehabilitation Projects
  The principles can assist in supplementing masonry structures with reinforcement or composite support elements, particularly where novel materials or atypical conditions exceed traditional design experience.

• Structural Assessment and National Annex Integration
  The standard allows flexibility in national applications through National Annexes, enabling the adoption of country-specific factors, such as tensile strength adjustments or shear capacity limits, thus supporting regional building code compliance.

Related Standards

• EN 845-2: Specification for Masonry Components - Lintels
  Defines requirements for prefabricated lintel parts including limits on built-in length relevant to composite lintel design.

• EN 1996-2: Design of Masonry Structures - Structural Tests
  Complements EN 1996-1-1 by providing standardized testing methods for masonry units and components.

• EN 1992-1-1: Design of Concrete Structures
  Relevant for reinforced masonry involving concrete elements or prefabricated concrete lintels.

• National Annexes to Eurocode 6
  Provide region-specific adaptations for material factors and safety coefficients, ensuring the standard’s applicability across European countries.
