15、on: Part 6: Sustainable development contributionsiv ISO 2015 All rights reserved ISO 15928-1:2015(E) Introduction This part of ISO 15928 is one 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

16、 15928- series is confined to buildings occupied for residential purposes that may be separated or linked horizontally, but not linked vertically, and which have their own access and do not share any common space. Each part of the ISO 15928- series relates to a separate attribute. The parts of ISO 1

17、5928 do not specify levels of performance and they are not intended to replace national standards or regulations, but provide a standardized framework to be used for development of national standards and regulations consistent with World Trade Organization (WTO) requirements. The parts of ISO 15928

18、do not provide design methods and/or design criteria. Based on the framework provided by the ISO 15928- series, purchasers, regulators and standards- preparers in respective countries can describe their requirements in standardized performance terms, as appropriate. Additionally, the manufacturers/p

19、roviders 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 standardized system of describing performance that can be used to specify performance requirements and performance levels, or to rate houses, in terms of st

20、ructural safety. NOTE The WTO Agreement on technical barriers to trade, Clause 2.8, states: “Whenever appropriate, members shall specify technical regulations based on product requirements in terms of performance, rather than design or descriptive characteristics.” ISO 2015 All rights reserved v Hou

21、ses Description of performance Part 1: Structural safety 1 Scope This part of ISO 15928 sets out a method for describing the structural safety performance of houses. It covers objectives, provides performance descriptions, establishes parameter descriptions, and outlines evaluation processes. It inc

22、ludes a description of permanent, imposed, wind, seismic, snow and other actions as well as structural resistance. 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, and in developing ris

23、k-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. It describes the structural safety of a house as a whole. NOTE 1 Annex A includes background information on this part of I

24、SO 15928, 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 serviceability, durability and other attributes are covered in other parts of ISO 15928. 2 Normative references The following documents

25、, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

27、use of deformation imposed on a structure or constrained within it Note 1 to entry: In North America, the term load is preferred and used in place of action. Note 2 to entry: In ISO 15928, the term load is used to indicate the value of a force corresponding to an action. Note 3 to entry: See ISO 670

28、7-1:2014, 9.3.22 for the definition of force.

33、tion of performance 4 Structural safety performance 4.1 Objective The structural capacity of a house to resist all actions which may affect the safety of the occupants of the house and may also lead to property damage to the house or an adjacent property, shall be such that the risk of collapse or o

34、ther kind of severe damage resulting from structural failure shall not exceed a level acceptable to the user. 4.2 Performance description The performance description is the capacity of the whole house and its parts, with an appropriate degree of reliability, to maintain their strength and stability

35、under all actions likely to occur.2 ISO 2015 All rights reserved ISO 15928-1:2015(E) The structural safety performance may be described by the magnitudes of the structural actions on the house and the resistance behaviour of the house under the effects of those actions. NOTE 1 The appropriate degree

36、 of reliability can be judged with due regard to the possible consequences of failure and the expense level of effort and procedures necessary to reduce the risk of failure. Aspects that are important in achieving the proper degree of reliability include choice of structural systems, design and anal

37、ysis, durability design, quality control, maintenance and protective measures. NOTE 2 For the purposes of this part of ISO 15928, the durability of materials are not considered to have a bearing on the structural performance of the house. 5 Parameters for the description of performance 5.1 Parameter

38、s for describing actions 5.1.1 Permanent actions The permanent actions, other than self-weight, are described by the magnitude(s) 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: a) a un

39、iformly distributed floor or roof load, in kilopascals, b) a concentrated floor or roof load, in kilonewtons, over a specified area, in square metres, c) a concentrated wall impact load, in kilonewtons, applied at a specified height, in metres, above the floor, and d) a uniformly distributed horizon

40、tal line load, in kilonewtons per metre, applied at a specified height, in metres, above the floor. NOTE 1 ISO 21031 provides minimum recommended imposed actions for different types of use and occupancy. NOTE 2 An example of d) is the load on a hand rail. 5.1.3 Wind actions Wind actions are describe

41、d by the representative value of the wind velocity, in metres per second, derived from the basic wind speed, factored as appropriate to take into account local effects, terrain, shielding, topography, altitude, etc., based on one of the following wind velocity types: a) 3-s gust; b) 1-min mean; c) 1

42、0-min mean; d) hourly mean. The effect of windborne debris on internal pressures should be considered. NOTE Refer to ISO 43542 for details on the conversion of wind velocity to wind forces and conversion between different types of wind velocity. ISO 2015 All rights reserved 3 ISO 15928-1:2015(E) 5.1

43、.4 Seismic actions Seismic actions are described by stating the representative value of one of the following parameters: a) the effective peak ground acceleration, expressed as a fraction of gravity; b) the base shear coefficient; c) the ground acceleration response spectrum for the site. The propor

44、tion 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 ISO 30103 provides additional

45、information on seismic action on structures. 5.1.5 Snow actions The snow actions are described by stating the representative values of: a) the ground snow depth, in metres, derived from the basic snow depth, factored to take into account local effects such as terrain, shielding, topography, etc.; b)

46、 the snow density, in kilograms per cubic metre, i.e. the density to be used in converting the ground snow depth into a load; and c) the duration, in days per year. NOTE ISO 43554 provides information on the conversion of ground snow depths to roof snow loads. 5.1.6 Other actions Consideration shall

47、 be given to the description of other actions arising from floods, tornados, tsunamis, potentially unstable sites, windborne debris, temperature, impact, explosion etc., if these actions are likely to affect the safety of the house. 5.1.7 Combinations of actions Consideration shall be given to the d

48、escription of the combinations of the actions to account for the probability of simultaneous occurrence of two or more actions. 5.2 Parameters for describing structural resistance 5.2.1 General The resistance of the house under the effects of the actions can be described in terms of limit state crit

49、eria or allowable stress criteria for materials with recognized engineering properties in accordance with 5.2.2 or 5.2.3 and ISO 2394 where appropriate. Materials without recognized engineering properties may be described in accordance with ISO 2394. Reference should be made to relevant International Standards when available. 5.2.2 Resistance based on limit state criteria The following information shall be provided: a) strength reduction factor (resistance factor or partial safety factors); b) characteristic m
