12、ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical
13、committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of elect
14、rotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the
15、member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ident
16、ifying any or all such patent rights. ISO 15928-2 was prepared by Technical Committee ISO/TC 59, Building construction, Subcommittee SC 15, Performance criteria for single family attached and detached dwellings. ISO 15928 consists of the following parts, under the general title Houses Description of
17、 performance: Part 1: Structural safety Part 2: Structural serviceability The following part is under preparation: Part 3: Structural durability BS ISO 15928-2:2005 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 27 08:35:54 GMT+00:00 2006, Uncontrolled Copy, (c) BSI v Introduction This part of
18、ISO 15928 is one of a series under the general title: Houses Description of performance. The objective of this series is to identify the methods used to describe the performance of houses. Each part will relate to a separate attribute. The parts specify levels of performance and they are not intende
19、d to replace national standards or regulations, but to provide a standardized framework to enable national standards and regulations to be developed in accordance with WTO requirements. The parts of ISO 15928 do not provide design methods and/or design criteria. Based on the framework provided by IS
20、O 15928, purchasers, regulators and standards writers in respective countries can describe their requirements in standardized performance terms. Additionally, the manufacturers/providers will be able to respond by describing the performance of their products in a similar manner. The purpose of ISO 1
21、5928 is to provide a standardized system that can be used to specify performance requirements and performance levels, or to rate houses in terms of structural serviceability. NOTE World trade organisation (WTO) Agreement on technical barriers to trade (WTO 1997), Clause 2.8, states that “Whenever ap
22、propriate, members shall specify technical regulations based on product requirements in terms of performance, rather than design or descriptive characteristics”.

This part o
24、f ISO 15928 covers user needs, provides performance descriptions, establishes parameter descriptions and outlines evaluation processes. This part of ISO 15928 is intended for use in the evaluation of the design and construction of houses, in the international trading of houses or their sub-systems,
25、and in developing quality systems for houses. This part of ISO 15928 does not apply to structural safety, durability or other attributes that are covered in other parts of ISO 15928. 2 Normative references The following referenced documents are indispensable for the application of this document. For
26、 dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、 structural serviceability performance NOTE Structural parameters consist of variables describing (i) magnitudes of the actions, (ii) magnitudes of structural response and (iii) other conditions that may affect the structural serviceability performance. 3.5 gitting fixture, such as shelving, cupboar
31、ds, equipment, etc., that is permanently fixed to the ceilings, walls, etc., of a house 3.6 performance behaviour of houses related to users needs 3.7 equipment hydraulic, mechanical electrical device that is provided for use within a house 3.8 component part of a house that can be identified EXAMPL
32、E Floor, wall. NOTE Includes fixtures. 3.9 structural serviceability performance structural behaviour of a house for normal use under all expected actions that might affect the occupants and the functioning of the house 4 Structural serviceability performance 4.1 User needs The following characteris
33、tics of a house, for normal use and conditions, under all expected actions, should be kept within levels acceptable to the user: a) functioning and appearance of the house and its components; b) functioning of the occupants in the house; c) functioning of the equipment in the house; d) comfort of th
34、e occupants; e) asset value of the house. NOTE The relative importance of each of these characteristics varies and is reflected in the performance requirements that are specified.

35、c) BSI 3 4.2 Performance description The performance description is the ability of the whole house and its parts, with an appropriate degree of reliability, to perform within established parameters under all expected actions for normal use in terms of a) local damage, including cracking, (which can
36、affect the efficiency and appearance of the house and its components), b) deformation (which can affect the efficient use or appearance of the house or the functioning of the people and equipments), c) vibration (which can cause discomfort or affect the activity of occupants or the functioning of eq
37、uipments). NOTE 1 The appropriate degree of reliability can be judged with due regard to the possible consequences of serviceability failure and the expense level of effort and procedures necessary to reduce those risk of failure. Aspects that are important in achieving the proper degree of reliabil
38、ity include choice of structural systems, design and analysis, durability design, quality control, maintenance and protective measures. NOTE 2 Expected actions for normal use can include those arising from soil/structure interaction, probable ground movements, compatibility of connections between su
39、bsystems and the effects of openings. NOTE 3 For the purposes of this standard, the durability of materials is not considered to have a bearing on the structural serviceability performance of the house. 4.3 Principles describing structural serviceability performance The structural serviceability per
40、formance can be described by the structural actions on the house under normal use and the structural responses under the effect of those actions. Only actions and responses relevant to serviceability issues of concern need to be described. NOTE For design specification, it is necessary to nominate t
41、he levels of structural actions and the acceptable limits of the structural responses corresponding to those levels of actions. 5 Parameters for the description of performance 5.1 Parameters for describing action 5.1.1 Permanent actions The permanent actions, other than self-weight, are described by
42、 the magnitude(s), expressed in kilonewtons, and the location(s) of the imposed load(s). 5.1.2 Imposed actions The imposed actions are described by the representative values of one or more of the following: a) uniformly distributed floor or roof load, expressed in kilonewtons per square metre: b) co
43、ncentrated floor or roof load, expressed in kilonewtons per: specified area, expressed in square metres; c) concentrated wall impact load, expressed in kilonewtons, applied at a specified height, expressed in metres, above the floor; d) uniformly distributed horizontal line load, expressed in kilone
44、wtons per metre, applied at a specified height, expressed in meters, above the floor. EXAMPLE A hand-rail. NOTE ISO 21031 provides minimum recommended imposed actions for different types of use and occupancy. BS ISO 15928-2:2005 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 27 08:35:54 GMT+00:
45、00 2006, Uncontrolled Copy, (c) BSI 4 5.1.3 Wind actions Wind actions are described by the representative value of the wind velocity, expressed in metres per second, under normal condition, derived from the basic wind speed, factored as appropriate to take into account local effects, terrain, shield
46、ing, topography, site altitude and the like, based on one of the following wind velocity types: a) 3 s gust; b) 1 min mean (fastest mile); c) 10 min mean; d) hourly mean. NOTE ISO 4354 2 provides details on the conversion of wind velocity to wind forces and the conversion between different types of
47、wind velocity. 5.1.4 Seismic actions Seismic actions are described by stating the representative value, under normal condition, of one of the following parameters: a) effective peak ground acceleration, expressed as a fraction of gravity; b) base shear coefficient; c) horizontal force applied to the
48、 structure, in kilonewtons, and its location; d) ground acceleration response spectrum for the site; e) floor acceleration response (for equipment and fittings). NOTE 1 Item e) relates to phenomena where equipment and/or fittings cannot be used due to the acceleration. If either a) or b) is used, th
49、en the proportion of the imposed loads to be included in the seismic mass shall also be nominated. The representative value shall be based on a consideration of the seismic activity, the soil characteristics of the construction site and the response behaviour of the structure. NOTE 2 ISO 3010 3 provides additional information on seismic action on structures. 5.1.5 Snow actions The snow actions are described by stating the representative values, under normal conditions, of the f
