1.1 Scope of EN 1997-3

(1) This document provides specific rules to be applied in the design and verification of geotechnical structures.

1.2 Assumptions

(1) This document is intended to be used in conjunction with EN 1990, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works.

NOTE Additional or amended provisions can be necessary for assessment of existing structures, see prEN 1990-2.

(2) This document is intended to be used in conjunction with EN 1997-1, which provides general rules for the design and verification of geotechnical structures.

(3) This document is intended to be used in conjunction with EN 1997-2, which gives provisions for determining ground properties from ground investigations.

(4) This document is intended to be used in conjunction with the other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures. 

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. 

1.1 Scope of EN 1998-4

(1) This document is applicable to the seismic design of on-ground and elevated silos, on-ground, elevated and underground tanks, above-ground and buried pipeline systems, towers, masts and chimneys and ancillary elements attached to these structures or in industrial facilities.

(2) Unless specifically stated, EN 1998-1-1 and EN 1998-5 apply.

(3) EN 1998-4 is applicable in complement to the other relevant Eurocodes.

NOTE This document contains only those provisions that, in addition to the provisions of the other relevant Eurocodes, are used for the design of new structures, as listed in (1), in seismic regions. EN 1998-4 complements in this respect the other Eurocodes.

1.2 Assumptions

(1) The assumptions of EN 1998-1-1 apply to this document.

(2) It is assumed that the changes in a) and b) will not take place during the construction phase or during the subsequent life span for all structures covered by EN 1998-4, unless proper justification and verification is provided:

a) substantial changes in the structural systems, supporting structures or attached ancillary elements listed in 1.1(1);

b) substantial changes of masses or mass distribution. This includes, in particular, changes in production, such as specific changes of filling loads, filling states and ancillary elements.

ISO 13164-2:2013 specifies a test method for the determination of radon-222 activity concentration in a sample of water following the measurement of its short-lived decay products by direct gamma-spectrometry of the water sample. The radon-222 activity concentrations, which can be measured by this test method utilizing currently available gamma-ray instruments, range from a few becquerels per litre to several hundred thousand becquerels per litre for a 1 l test sample. This test method can be used successfully with drinking water samples. The laboratory is responsible for ensuring the validity of this test method for water samples of untested matrices. An annex gives indications on the necessary counting conditions to meet the required sensitivity for drinking water monitoring.

This document establishes the organizational, design, construction, operational, and quality-assurance requirements applicable to heterogeneous, thermal-spectrum research reactors with power levels up to several tens of megawatts. It defines the minimum expectations for management structure, project governance, safety culture, quality assurance, documentation control, and lifecycle oversight necessary to

ensure safe, compliant, and effective reactor operation.

The document applies to new research reactors and, where practicable, to existing or legacy reactors using a graded approach consistent with IAEA SSR-3[6] a nd I AEA S SG-22.[10] It addresses administrative and operational controls, procurement and inspection processes, training and qualification, radiation protection, and change management throughout the reactor lifecycle, including modifications and decommissioning.

This document does not prescribe detailed technical design specifications; rather, it provides the framework within which such specifications are developed, reviewed, and controlled. Additional guidance may be required for reactors exceeding the stated power range or for specialized reactor types such as fast spectrum systems or facilities incorporating advanced experimental features.

This document specifies a thermal method and a gravimetric method for a quantitative determination of the certain synthetic materials (polyester, polyamide, acrylic, elastane, polypropylene and polyethylene) released from fabrics under washing test conditions.

This method is applicable to synthetic fabric and synthetic/natural blended fabric

- Synthetic/protein fabrics (e.g. PET/Wool, Nylon/Wool, Acrylic/Wool)

This document specifies the characteristics and the requirements of unrestricted air gap Family A, Type A for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document applies to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use. The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests could be required to verify the efficacy of the solution in practical use. The AA device is intended to be used in potable water installations according to EN 806 (series). Sanitary tapware when installed onto a receiving vessel (e.g. washbasin etc.) might have some restriction of its overflow. This will not compromise the water supply as the tapware might have an air gap, as detailed for example in EN 200 (dimension E), that provides an air gap disconnection. If this is the case, then backflow protection will be assumed to be adequate, and no further testing/verification will be needed.

ISO 25178-70:2014 specifies the characteristics of material measures used for the periodic verification and adjustment of areal surface texture measurement instruments.
