Bases for design of structures — General principles on seismically isolated structures

ISO 23618:2022(Main)

This document specifies the principles regarding the design of seismically isolated structures under earthquake effects. This document also describes the principles of construction management and maintenance, since proper construction management and maintenance are important for realizing high quality seismic isolation structures. This document is not applicable to bridges and LNG tanks, although some of the principles can be referred to for the seismic isolation of those structures. This document is not applicable to seismic isolation structures that reduce the vertical response to earthquake ground motions, since this document mainly specifies seismic isolation structures that attenuate the horizontal response to horizontal earthquake ground motions. This document is not a legally binding and enforceable code. It can be viewed as a source document that is utilized in the development of codes of practice by the competent authority responsible for issuing structural design regulations. NOTE This document has been prepared mainly for the seismically isolated structures which have the seismic isolation interface applied between a superstructure and a substructure to reduce the effect of the earthquake ground motion onto the superstructure. In most cases, the substructure refers to the foundation of the structure. However, the substructure in this document consists of a structural system below the isolation interface that has been designed with sufficient rigidity and strength. Examples include locating the isolation interface in a mid-storey of the building or above the bridge piers (see Annex E).

Houses — Description of performance — Part 7: Accessibility and usability

ISO 15928-7:2021(Main)

This document sets out a method for describing the performance of houses. It covers user needs, provides performance descriptions, and outlines evaluation processes. It includes the description of relevant parameters necessary to ensure accessibility and usability in houses. It also includes features to ensure safety during daily use, i.e., reasonable consideration to prevent accident like tripping, falls, or collision. This document is intended for use in the evaluation of the design and construction of houses, in the international trading of houses or their sub-systems, and in developing risk-management tools for the protection of houses. It does not specify a level of performance and it is not intended to provide design method and/or criteria. NOTE 1 Structural safety, fire safety, and other performance attributes of a house are covered in other parts of the ISO 15928 series. NOTE 2 Exporting a house (as a complete set, “kit house” for example) does mean that the site is not necessarily predetermined. Therefore, surrounding conditions cannot be known in advance. Even the interface between the entrance door and the ground cannot be predetermined (including how flat entry can be achieved). It is up to the builder and the client to decide how to design the interface. However, design examples for accessibility can be given. NOTE 3 The way to describe performance of buildings is given in ISO 19208.

Test methods for determining the contribution to the fire resistance of structural members - Part 1: Horizontal protective membranes

EN 13381-1:2020

This document specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of standard horizontal structural building members as defined in 6.4.2.
Test of horizontal protective membrane installed under a specific non-standard floor should be tested according to EN 1365-2.
This document contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied from below the membrane itself.
The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2.
This document also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member.
In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex C.
The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings.
This documentapplies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise, the test methods in EN 13381-3, EN 13381 4 or EN 13381-5, as appropriate, apply.
Tests are intended to be carried out without additional combustible materials in the cavity.
Annex A gives details of assessing the performance of the ceiling when exposed to a semi-natural fire.

Bases for design of structures — General principles on risk assessment of systems involving structures

ISO 13824:2020(Main)

This document specifies general principles of risk assessment for systems involving structures. The focus is on strategic and operational decision-making related to design, assessment, maintenance and decommissioning of structures. This also includes formulation and calibration of related codes and standards. Systems involving structures can expose stakeholders at various levels in society to significant risks. The aim of this document is to facilitate and enhance decision-making with regard to monitoring, reducing and managing risks, and preparing for emergency in an efficient, cost-effective and transparent manner. Within the broader context of risk management, risk assessment provides decision-makers with procedures to determine whether or not, and in what manner, it is appropriate to treat risks. This document provides a general framework as well as a procedure for identifying hazards and estimating, evaluating and treating risks of structures and systems involving structures. This document also provides a basis for code writers as well as designers to set reasonable target-reliability levels, such as stated in ISO 2394, based on the result of risk considerations. For existing structures, it is intended that assessment of the risks associated with the events that were not considered in the original design or with changes in use be implemented according to the principles stated in this document. This document can also be used for risk assessment of exceptional structures upon specific adaptation and detailing, the design of which is not usually within the scope of existing codes.

Bases for design of structures — General requirements

ISO 22111:2019(Main)

This document provides the requirements for structural design and procedures following a semi-probabilistic approach that conform to the general principles for structural reliability as stipulated by ISO 2394. The scope of requirements and procedures are accordingly limited to the design of structures for which sufficient knowledge and experience are commonly available on design and construction practice to ensure that target levels of reliability account for the nature and consequences of structural failure. Situations outside these limitations are covered by ISO 2394. The methods that are included in this document are the semi-probabilistic limit states approaches that are proven to achieve sufficient and consistent levels of structural reliability. This document relies on standardized procedures for the characterization of the load bearing performance of the structures within its scope. Sufficient information is needed on uncertainties of design variables and models to be able to derive semi-probabilistic design measures for verification of structural reliability within the scope of this and the related design standards.

Bases for design of structures — Seismic actions on structures

ISO 3010:2017(Main)

ISO 3010:2017 (including both the super structure and foundation) and other structures. ISO 3010:2017 is not applicable to certain structures, such as bridges, dams, geotechnical works and tunnels, although some of the principles can be referred to for the seismic design of those structures. ISO 3010:2017 is not applicable to nuclear power plants, since these are dealt with separately in other International Standards. In regions where the seismic hazard is low, methods of design for structural integrity can be used in lieu of methods based on a consideration of seismic actions. ISO 3010:2017 is not a legally binding and enforceable code. It can be viewed as a source document that is utilized in the development of codes of practice by the competent authority responsible for issuing structural design regulations. NOTE 1 This document has been prepared mainly for new engineered structures. The principles are, however, applicable to developing appropriate prescriptive rules for non-engineered structures (see Annex N). The principles could also be applied to evaluating seismic actions on existing structures. NOTE 2 Other structures include self-supporting structures other than buildings that carry gravity loads and are required to resist seismic actions. These structures include seismic force-resisting systems similar to those in buildings, such as a trussed tower or a pipe rack, or systems very different from those in buildings, such as a liquid storage tank or a chimney. Additional examples include structures found at chemical plants, mines, power plants, harbours, amusement parks and civil infrastructure facilities. NOTE 3 The level of seismic hazard that would be considered low depends not only on the seismicity of the region but also on other factors, including types of construction, traditional practices, etc. Methods of design for structural integrity include nominal design horizontal forces (such as an equivalent static loading determined from a simplified equivalent static analysis) which provide a measure of protection against seismic actions.

Atmospheric icing of structures

ISO 12494:2017(Main)

ISO 12494:2017 describes the general principles of determining ice load on structures of the types listed in this clause. In cases where a certain structure is not directly covered by this or another standard or recommendation, designers can use the intentions of this document. However, it is the user's responsibility to carefully consider the applicability of this document to the structure in question. The practical use of all data in this document is based upon certain knowledge of the site of the structure. Information about the degree of "normal" icing amounts (= ice classes) for the site in question is used. For many areas, however, no information is available. Even in such cases, this document can be useful because local meteorologists or other experienced persons should be able to, on the safe side, estimate a proper ice class. Using such an estimate in the structural design will result in a much safer structure than designing without any considerations for problems due to ice. CAUTION It is extremely important to design for some ice instead of no ice, and then the question of whether the amount of ice was correct is of less importance. In particular, the action of wind can be increased considerably due to both increased exposed area and increased drag coefficient. ISO 12494:2017 is intended for use in determining ice mass and wind load on the iced structure for the following types of structure: - masts; - towers; - antennas and antenna structures; - cables, stays, guy ropes, etc.; - rope ways (cable railways); - structures for ski-lifts; - buildings or parts of them exposed to potential icing; - towers for special types of construction such as transmission lines, wind turbines, etc. Atmospheric icing on electrical overhead lines is covered by IEC (International Electrotechnical Commission) standards. This document is intended to be used in conjunction with ISO 2394. NOTE Some typical types of structure are mentioned, but other types can also be considered by designers by thinking in terms of which type of structure is sensitive to unforeseen ice, and act thereafter. Also, in many cases, only parts of structures are to be designed for ice loads because they are more vulnerable to unforeseen ice than is the whole structure. Even if electrical overhead lines are covered by IEC standards, designers can use this document for the mast structures to overhead lines (which are not covered by IEC standards) if they so wish.

Bases for design of structures — Determination of snow loads on roofs

ISO 4355:2013(Main)

ISO 4355:2013 specifies methods for the determination of snow load on roofs. It can serve as a basis for the development of national codes for the determination of snow load on roofs. National codes should supply statistical data of the snow load on ground in the form of zone maps, tables, or formulae. The shape coefficients presented in ISO 4355:2013 are prepared for design application, and can thus be directly adopted for use in national codes, unless justification for other values is available. For determining the snow loads on roofs of unusual shapes or shapes not covered by ISO 4355:2013 or in national standards, it is advised that special studies be undertaken. These can include testing of scale models in a wind tunnel or water flume, especially equipped for reproducing accumulation phenomena, and should include methods of accounting for the local meteorological statistics. Examples of numerical methods, scale model studies, and accompanying statistical analysis methods are described in ISO 4355:2013 (Annex G). The annexes of ISO 4355:2013 describing methods for determining the characteristic snow load on the ground, exposure coefficient, thermal coefficient, and loads on snow fences are for information only as a consequence of the limited amount of documentation and available scientific results. In some regions, single winters with unusual weather conditions can cause severe load conditions not taken into account by ISO 4355:2013. Specification of standard procedures and instrumentation for measurements is not dealt with in ISo 4355:2013.

Test methods for determining the contribution to the fire resistance of structural members - Part 6: Applied protection to concrete filled hollow steel columns

EN 13381-6:2012

This European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete filled hollow steel columns. The concrete can be lightweight, normalweight or heavyweight concrete, and of all the strength classes provided for in EN 1994-1-2. The use of a dry sand is considered to be an alternative, conservative approach to the use of wet concrete. A specification for dry sand is given in 5.6.3. The method is applicable to all fire protection systems used for the protection of concrete filled hollow columns and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. If there is no hollow section data from prEN 13381-4 (revision of ENV 13381-4:2002) or prEN 13381-8 (revision of EN 13381-8:2010), this European Standard cannot be used. For passive systems, this data can be derived using the Formula in Annex A of prEN 13381-4 (revision of ENV 13381-4:2002). Testing to this European Standard is not required if the fire protection thicknesses for hollow sections derived from prEN 13381-4 (revision of ENV 13381-4:2002) or prEN 13381-8 (revision of EN 13381-8:2010) are to be used for concrete filled hollow sections. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterized by their diameters and wall thicknesses, a range of design temperatures and a range of valid fire protection classification periods. The test method is applicable to fire protection systems which are intimately in contact with the structural column, or which include an airspace between the structural column and the protection system. This European Standard specifies the fire tests which are carried out to determine the ability of the fire protection system to provide fire protection to composite columns. The tests produce data on the average steel temperatures of the composite column, when exposed to the time/temperature curve according to the procedures defined herein. This European Standard also provides the assessment procedure, which prescribes how the analysis of the test data should be made and gives guidance on the procedures by which interpolation is undertaken. In special circumstances, where specified in national building regulations, there can be a need to subject reactive protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in prEN 13381-8 (revision of EN 13381-8:2010). This exposure, applicable to reactive fire protection materials, is used only in special circumstances (which are specified in the national building regulations of a member state of the European Union) and is therefore not intended to be mandatory for all fire protection materials applied to concrete filled hollow steel columns. This European Standard ignores any contribution from the concrete to the structural capability of the hollow column and therefore only deals with thermal performance. The justification for using this approach is given in Annex B. The fire test methodology makes provision for the collection and presentation of data which can be used as direct input to the calculation of fire resistance of concrete/steel composite members in accordance with the procedures given in EN 1994-1-2.

Bases for design of structures — Assessment of existing structures

ISO 13822:2010(Main)

ISO 13822:2010 provides general requirements and procedures for the assessment of existing structures (buildings, bridges, industrial structures, etc.) based on the principles of structural reliability and consequences of failure. It is based on ISO 2394. ISO 13822:2010 is applicable to the assessment of any type of existing structure that was originally designed, analysed and specified based on accepted engineering principles and/or design rules, as well as structures constructed on the basis of good workmanship, historic experience and accepted professional practice. The assessment can be initiated under the following circumstances: an anticipated change in use or extension of design working life; a reliability check (e.g. for earthquakes, increased traffic actions) as required by authorities, insurance companies, owners, etc.; structural deterioration due to time-dependent actions (e.g. corrosion, fatigue); structural damage by accidental actions (see ISO 2394). ISO 13822:2010 is also applicable to heritage structures provided additional considerations shown in Annex I are taken into account. ISO 13822:2010 is applicable to existing structures of any material, although specific adaptation can be required depending on the type of material, such as concrete, steel, timber, masonry, etc. ISO 13822:2010 provides principles regarding actions and environmental influences. Further detailed considerations are necessary for accidental actions such as fire and earthquake. ISO 13822:2010 is intended to serve as a basis for preparing national standards or codes of practice in accordance with current engineering practice and the economic conditions.

ISO 4354:2008 describes the actions of wind on structures and specifies methods of calculating characteristic values of wind loads for use in designing buildings, towers, chimneys, bridges and other structures, as well as their components and appendages. The loads are suitable for use in conjunction with ISO 2394 and other International Standards concerned with wind loads. In particular, ISO 4354:2008 facilitates the conversion between peak- and mean-wind-speed methodologies and covers the three main storm types, synoptic winds, thunderstorms and tropical cyclones (hurricanes and typhoons). ISO 4354:2008 provides the basic methods from which to determine wind loading analytically through the determination of design pressures or orthogonal along-wind and cross-wind forces and moments for structures of simple shape and wind directionality effects, and through wind tunnel or computational determinations of pressure, forces and moments for structures with complex shapes and wind directionality effects resulting in complex combinations of forces and moments. Two methods of analytical determination of design wind loads are given, one based on a peak velocity and the other on a mean velocity.

General principles on the design of structures for durability

ISO 13823:2008(Main)

ISO 13823:2008 specifies general principles and recommends procedures for the verification of the durability of structures subject to known or foreseeable environmental actions, including mechanical actions, causing material degradation leading to failure of performance. It is necessary to insure reliability of performance throughout the design service life of the structure. Fatigue failure due to cyclic stress is not within the scope of ISO 13823:2008.

Bases for design of structures — Seismic actions for designing geotechnical works

ISO 23469:2005(Main)

ISO 23469:2005 provides guidelines for specifying seismic actions for designing geotechnical works, including buried structures (e.g. buried tunnels, box culverts, pipelines, and underground storage facilities), foundations (e.g. shallow and deep foundations, and underground diaphragm walls), retaining walls (e.g. soil retaining and quay walls), pile-supported wharves and piers, earth structures (e.g. earth and rockfill dams and embankments), gravity dams, landfill and waste sites. The guidelines provided in ISO 23469:2005 are general enough to be applicable for both new and existing geotechnical works. However, for use in practice, procedures more specific to existing geotechnical works can be needed, such as those described for existing structures in ISO 13822.

Hygrothermal performance of building components and building elements - Assessment of moisture transfer by numerical simulation

EN 15026:2007(Main)

SIST EN 15026:2007

This standard specifies the equations to be used in a simulation method for calculating the non steady transfer of heat and moisture through building structures.
It also provides a benchmark example intended to be used for validating a simulation method claiming conformity with this standard, together with the allowed tolerances.
The equations in this standard take account of the following storage and one-dimensional transport phenomena:
-   heat storage in dry building materials and absorbed water;
-   heat transport by moisture-dependent thermal conduction;
-   latent heat transfer by vapour diffusion;
-   moisture storage by vapour sorption and capillary forces;
-   moisture transport by vapour diffusion;
-   moisture transport by liquid transport (surface diffusion and capillary flow).
The equations described in this standard account for the following climatic variables:
-   internal and external temperature;
-   internal and external humidity;
-   solar and longwave radiation;
-   precipitation (normal and driving rain);
-   wind speed and direction.
The hygrothermal equations described in this standard shall not be applied in cases where:
-   convection takes place through holes and cracks;
-   two-dimensional effects play an important part (e.g. rising damp, conditions around thermal bridges, effect of gravitational forces);
•   hydraulic, osmotic, electrophoretic forces are present;
daily mean temperatures in the component exceed 50 °C.

Test methods for determining the contribution to the fire resistance of structural members - Part 1: Horizontal protective membranes

CEN/TS 13381-1:2005

This Part of this European Prestandard specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of horizontal structural building members.
This European Technical Specification contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied to the side which would be exposed in practice and from below the membrane itself.
The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2.
A related test method for determining the contribution to the fire protection of vertical structural members by vertical protective membranes is given in Part 2 of this ENV.
This European Technical Specification also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member.
The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings.
This European Technical Specification applies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise the test methods in ENV 13381-3, ENV 13381-4 or ENV 13381-5, as appropriate, apply.
Tests shall be carried out without additional combustible materials in the cavity.
