14、neering works, Subcommittee SC 15, Performance description of houses. This second edition cancels and replaces the first edition (ISO 15928-2:2005), which has been technically revised. ISO 15928 consists of the following parts, under the general title Houses Description of performance: Part 1: Struc

15、tural safety Part 2: Structural serviceability Part 3: Structural durability Part 4: Fire safety Part 5: Operating energy The following part is under preparation: Part 6: Sustainable development contributionsiv ISO 2015 All rights reserved ISO 15928-2:2015(E) Introduction This part of ISO 15928 is o

16、ne of a series of standards. The objective of the ISO 15928- series is to identify the methods that will be used to describe the performance of houses. The ISO 15928- series is confined to buildings occupied for residential purposes that may be separated or linked horizontally, but not linked vertic

17、ally, and which have their own access and do not share any common space. Each part of ISO 15928 relates to a separate attribute. The parts of ISO 15928 do not specify levels of performance and they are not intended to replace national standards or regulations, but provide a standardized framework to

18、 be used for development of national standards and regulations consistent with World Trade Organization (WTO) requirements. The parts of ISO 15928 do not provide design methods and/or design criteria. Based on the framework provided by the ISO 15928- series, purchasers, regulators and standards- pre

19、parers in respective countries can describe their requirements in standardized performance terms, as appropriate. Additionally, the manufacturers/providers can respond by describing the performance of their products in a similar manner. The purpose of this part of ISO 15928 is to provide a standardi

20、zed system of describing performance that can be used to specify performance requirements and performance levels, or to rate houses, in terms of structural serviceability. NOTE The WTO Agreement on technical barriers to trade, Clause 2.8, states: “Whenever appropriate, members shall specify technica

21、l regulations based on product requirements in terms of performance, rather than design or descriptive characteristics.” ISO 2015 All rights reserved v Houses Description of performance Part 2: Structural serviceability 1 Scope This part of ISO 15928 sets out a method for describing the structural s

22、erviceability performance of houses. It covers objectives, 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 h

23、ouses or their sub-systems, and in developing risk-management tools for the protection of houses. The ISO 15928- series does not specify a level of performance and it is not intended to provide a design method and/or criteria. NOTE 1 Annex A includes background information on this part of ISO 15928,

24、 guidance on its use, and suggestions on good practice. NOTE 2 Details on references referred to in Notes are provided in a Bibliography. NOTE 3 Structural safety, durability and other attributes are covered in other parts of ISO 15928. 2 Normative references The following documents, in whole or in

34、Objective The structural behaviour of a house, for normal use under all expected actions, that may affect the occupants and the functioning of the house, shall be such that the following characteristics of a house shall be kept within levels acceptable to the user: a) functioning and appearance of t

35、he house and its components; b) functioning of the occupants in the house; c) functioning of the equipment in the house; d) comfort of the occupants. NOTE The relative importance of each of these characteristics varies and is reflected in the performance requirements that are specified. 4.2 Performa

36、nce 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 efficienc

37、y 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 equipment), c) vibration (which can cause discomfort or affect the activity of occupants or the functioning of equipment). The structu

38、ral serviceability performance 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 1 The appropriate degree of relia

39、bility 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 structural systems, design

40、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 of openings. NOTE 3 For

41、the purposes of this part of ISO 15928, the durability of materials is not considered to have a bearing on the structural serviceability performance of the house. NOTE 4 For design specification, it is necessary to nominate the levels of structural actions and the acceptable limits of the structural

42、 responses corresponding to those levels of actions. 5 Parameters for the description of performance 5.1 Parameters for describing actions 5.1.1 Permanent actions The permanent actions, other than self-weight, are described by the magnitude(s), expressed in kilonewtons, and the location(s) of the im

43、posed load(s). ISO 2015 All rights reserved 3 ISO 15928-2:2015(E) 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 roo

44、f 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

45、 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. 5.1.3 Wind actions Wind actions are described by the representative value of the wind velocity, expressed in metres

46、 per second, under normal conditions, 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) 3 s gust; b) 1 min mean (fastest mile); c) 10 min mea

47、n; d) hourly mean. NOTE ISO 43542 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 value, under normal conditions, of one of the following

48、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 site; e) floor acceleration response (for equipment and f

49、ittings). 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. 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 30103 provides additional information on seismic action on structures.4 ISO 2015
