9、-,- ISO 15928-2:2005(E) iv ISO 2005 All rights reserved Foreword 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
10、. Each member body interested in a subject for which a technical 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 Intern
11、ational Electrotechnical Commission (IEC) on all matters of electrotechnical 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 Sta
12、ndards adopted by the technical committees are circulated to the 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 subj
13、ect of patent rights. ISO shall not be held responsible for identifying 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 t
14、he following parts, under the general title Houses Description of performance: Part 1: Structural safety Part 2: Structural serviceability The following part is under preparation: Part 3: Structural durability ISO 15928-2:2005(E) ISO 2005 All rights reserved v Introduction This part of ISO 15928 is
15、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 intended to replace
16、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 ISO 15928, purc
17、hasers, 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 15928 is to pr
18、ovide 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 appropriate, me
19、mbers shall specify technical regulations based on product requirements in terms of performance, rather than design or descriptive characteristics”. -,-,- -,-,- INTERNATIONAL STANDARD ISO 15928-2:2005(E) ISO 2005 All rights reserved 1 Houses Description of performance Part 2: Structural serviceabili
20、ty 1 Scope This part of ISO 15928 sets out a method for describing the structural serviceability performance of houses. This part of ISO 15928 covers user needs, provides performance descriptions, establishes parameter descriptions and outlines evaluation processes. This part of ISO 15928 is intende
21、d 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 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
22、of ISO 15928. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

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
29、 performance 4.1 User needs The following characteristics 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) functi
30、oning of the equipment in the house; d) comfort of the 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. ISO 15928-2:2005(E) ISO 2005 All rights reserved 3 4.2 Performance
31、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 affect the efficiency and
32、 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 equipments). NOTE 1 The app
33、ropriate 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 reliability include choice of str
34、uctural 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 subsystems and the effects
35、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 performance can be described
36、 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 the levels of structural a
37、ctions 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 the magnitude(s), expres
38、sed 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) concentrated floor or roof
39、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 kilonewtons per metre, applied
40、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. -,-,- ISO 15928-2:2005(E) 4 ISO 2005 All rights reserved 5.1.3 Wind actions Wind actions are described by the repres
41、entative 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, shielding, topography, site altitude and the like, based on one of the following wind velocity types: a
42、) 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 wind velocity. 5.1.4 Seismic actions Seismic actions are described by stating the representative
43、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 structure, in kilonewtons, and its location; d) ground acceleration response spectrum for the si
44、te; 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, then the proportion of the imposed loads to be included in the seismic mass shall also be nominated
45、. 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
46、are described by stating the representative values, under normal conditions, of the following: a) ground snow depth, expressed in metres, derived from the basic snow depth, factored to take into account local effects such as terrain, shielding, topography and the like; b) snow density, expressed in
47、kilograms per cubic metre, i.e., the density used in converting the ground snow depth into a load; c) duration, in days per year. NOTE ISO 4355 4 provides information on the conversion of ground snow depths to roof snow loads. -,-,- ISO 15928-2:2005(E) ISO 2005 All rights reserved 5 5.1.6 Vibration
48、sources Consideration shall be given to the description of vibration sources inside and outside the house, such as that caused by machinery, vehicular traffic and human activity, if these sources affect the occupants of the house on a regular basis. NOTE ISO 10137 5 provides information on the description of vibration sources. 5.1.7 Impact sources If these impacts are likely to occur during normal use, consideration shall be given to the description of impact sources due to human activities or the environment in terms of the following: a) specified in mass, expressed in kilograms; b)
