1.1 Scope of EN 1998-3 (1) This document is applicable to the assessment and retrofitting of buildings and bridges in seismic regions, namely as given in a) to c): a) to provide criteria for the assessment of the seismic performance of existing individual buildings and bridges; b) to describe the procedure to be followed in selecting necessary corrective measures; c) to set forth criteria for the design of retrofitting measures (i.e. design, structural analysis including intervention measures, final dimensioning of structural parts and their connections to existing structural members). NOTE 1 For the purposes of this document, retrofitting covers both the seismic upgrading (e.g. strengthening or adding a passive system) of undamaged structures and the repair and possible upgrading of earthquake-damaged structures. NOTE 2 Only the most common retrofit techniques are covered in this document. This does not exclude the use of other techniques, which can be developed in each country, based on the strengthening principles of this document. NOTE 3 Annex D gives flowcharts for the application of this document. (2) Unless specifically stated, EN 1998-1-1 and EN 1998-5 apply. (3) Reflecting the performance requirements of EN 1998-1-1:2024, 4.1, this document covers the seismic assessment and retrofitting of buildings and bridges made of the more commonly used structural materials: concrete, steel and composite, timber and masonry. NOTE Annexes B and C contain additional guidance related to the assessment of timber and masonry structures, respectively, and to their retrofitting when necessary. (4) This document is intended for the assessment of individual structures, to decide on the need for structural intervention and to design the retrofitting measures that may be necessary. It is not intended for the vulnerability assessment of populations or groups of structures in seismic risk evaluations for various purposes (e.g. for determining insurance risk, for setting risk mitigation priorities, etc.). (5) This document provides (in its material-specific Clauses 8 to 11) criteria for the verification of the more common retrofitting techniques currently in use. (6) This document gives specific rules for the assessment and retrofitting relevant to existing buildings and bridges of consequence classes CC1, CC2 and CC3, as defined in EN 1990:2023, 4.3. (7) Although the provisions of this document are applicable to all common categories of buildings and bridges, the seismic assessment and retrofitting of monuments and heritage structures often requires different types of provisions and approaches, depending on the nature of the monuments and heritage structures. 1.2 Assumptions (1) The assumptions of EN 1998-1-1 apply to this document. (2) The provisions of this document assume that the data collection and tests are performed by experienced personnel and that the engineer responsible for the assessment, the possible design of the retrofitting and the execution of work has appropriate experience of the type of structures being upgraded or repaired. (3) It is assumed that inspection procedures, checklists and other data-collection procedures will be documented and filed and referred to in the assessment/design documents.

1.1 Scope of EN 1991-1-3 (1) EN 1991-1-3 gives principles and rules to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works. (2) This document does not apply to sites at altitudes above 1 500 m, unless otherwise specified. NOTE For rules for the treatment of snow loads for altitudes above 1 500 m, see 6.1. (3) This document does not give guidance on specialist aspects of snow loading, for example: - impact snow loads resulting from snow sliding off or falling from a higher roof; - changes in shape or size of the construction works due to the presence of snow or the accretion of ice which could affect the wind action; - loads in areas where snow is present all year round; - lateral loading due to snow creep (e.g. lateral loads exerted by drifts); - loads due to artificial snow. 1.2 Assumptions The assumptions given in EN 1990:2023, 1.2 apply.

1.1 Scope of EN 1996-3 (1) This document provides simplified calculation methods to facilitate the design of the following unreinforced masonry walls, subject to certain conditions of application: - walls subjected to vertical and wind loading; - walls subjected to concentrated loads; - shear walls; - basement walls subjected to lateral earth pressure and vertical loading; - walls subjected to lateral loading but not subjected to vertical loading. NOTE 1 For those types of masonry structures or parts of structures not covered by (1), the design can be based on EN 1996-1-1. NOTE 2 The rules given in this document are consistent with those given in EN 1996-1-1 but are more conservative in respect of the conditions and limitations of their use. (2) This document applies only to those masonry structures, or parts thereof, that are described in EN 1996-1-1 and EN 1996-2. (3) The simplified calculation methods given in this document do not cover the design of double-leaf walls. (4) The simplified calculation methods given in this document do not cover the design for accidental situations. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document. (2) This document is intended to be used, for direct application, together with EN 1990, the EN 1991 series, EN 1996 1-1, EN 1996-1-2 and EN 1996-2. (3) The rules given in this document assume that concrete floors are designed according to EN 1992-1-1.

(1) The basis for the design of building and civil engineering works in masonry is given in this Part 1-1 of EN 1996, which deals with unreinforced masonry, reinforced masonry and confined masonry. Principles for the design of prestressed masonry are also given. This Part 1-1 of EN 1996 is not valid for masonry elements 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 provisions given in this Part 1-1 of EN 1996 may be applicable, but may need to be supplemented. (3) Part 1-1 of EN 1996 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. (4) Part 1-1 of EN 1996 does not cover: - resistance to fire (which is dealt with in EN 1996-1-2); - particular aspects of special types of building (for example, dynamic effects on tall buildings); - particular aspects of special types of civil engineering works (such as masonry bridges, dams, chimneys or liquid-retaining structures); - particular aspects of special types of structures (such as arches or domes); - masonry where gypsum, with or without cement, mortars are used; - masonry where the units are not laid in a regular pattern of courses (rubble masonry); - masonry reinforced with other materials than steel.
