The work of preparing International Standards is normally carried out through ISO tec
17、hnical committees. 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 closel
18、y with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria nee
19、ded for the different types of ISO documents should be noted.

22、roductionThis International Standard presents basic principles for the evaluation of seismic actions on architectural, mechanical and electrical components and systems (i.e. nonstructural components) in building applications. The seismic actions described are fundamentally compatible with ISO 2394.1
23、This International Standard is intended to be a companion document to ISO 3010, Basis for design of structures Seismic actions on structures. It includes not only principles of seismic design but also procedures for the verification of component and system capacity to ensure that those capacities ex
24、ceed seismic demands. Full verification of components and systems adequacy generally includes other actions not addressed by this International Standard in combination with seismic actions.This International Standard includes limit states associated with post-earthquake functionality of nonstructura
25、l components. Some of these limit states address the overall safety of the building occupants, while others address the safety of the surrounding community impacted by functional failure of the facility. It therefore includes requirements for equipment and systems that demonstrate that they will fun
26、ction as needed to achieve the overall safety goals following the earthquake.The approach used in this International Standard is to first define the goals and performance objectives and then determine the seismic demands on nonstructural components and systems. The seismic demands, which are complex
27、 in nature, are initially described in a general way. Then, based on reasonable assumptions, seismic demands are quantified in a simple manner that is efficient for use in most situations. The simplified demands are based on the assumption that the seismic response of nonstructural components and sy
28、stems have a negligible effect on the primary response of the structure. A series of annexes included with this International Standard provide informative guidance on determining simplified coefficients, performing evaluation of components, and implementing alternative testing/empirical procedures u
29、sed for verification including those needed to demonstrate functionality to achieve the overall post-earthquake safety goals.vi ISO 2013 All rights reservedBS ISO 13033:2013Bases for design of structures Loads, forces and other actions Seismic actions on nonstructural components for building applica
30、tions1 Scope1.1 GeneralThis International Standard establishes the means to derive seismic actions on nonstructural components and systems (NSCS) supported by or attached to new or existing buildings. It also provides procedures for the verification of NSCS seismic capacities. NSCS include architect
31、ural elements, mechanical and electrical systems, and building contents.This International Standard is not a legally binding and enforceable code. It is a source document that is utilized in the development of codes of practice by the competent authority responsible for issuing structural design reg
32、ulations. This International Standard is intended for application by regional and national standards committees when preparing standards for the seismic performance of NSCS.This International Standard does not specifically cover industrial facilities, including nuclear power plants, since these are
33、dealt with separately in other International Standards. However, the principles in this International Standard can be appropriate for the derivation of seismic actions for NSCS in such facilities.NOTE 1 This International Standard has been prepared mainly for NSCS associated with engineered building
34、s. The principles are, however, applicable to non-engineered buildings.NOTE 2 Procedures for the verification of the supporting building structure for gravity and seismic actions applied by the NSCS are outside the scope of this International Standard and are provided in ISO 3010.1.2 Relationship wi
35、th ISO 3010This International Standard is a companion document to ISO 3010, Basis for design of structures Seismic actions on structures. ISO 3010 and its annexes provide basic seismic design criteria to be used in the design of structures but they do not provide design criteria for NSCS (except for
36、 those that can influence the structural response). For consistency, the terms and definitions that are in common with ISO 3010 are also used in this International Standard.The same ground motion criteria specified in ISO 3010 are also used in this International Standard. The demand on NSCS is direc
37、tly related to the response of the building in which they are located. Therefore, the procedures used to determine the design ground motion and building seismic response are directly referenced by this International Standard.1.3 Components requiring evaluationEvaluation of NSCS for seismic actions i
38、s required where any of the following apply:a) the NSCS poses a falling hazard;b) the failure of the NSCS can impede the evacuation of the building;c) the NSCS contains hazardous materials;d) the NSCS is necessary to the continuing function of essential facilities after the event; ande) damage to th
39、e NSCS represents a significant financial loss.INTERNATIONAL STANDARD ISO 13033:2013(E) ISO 2013 All rights reserved 1BS ISO 13033:2013ISO 13033:2013(E)Guidance for identification of NSCS that require seismic evaluation is provided in Annex A.NOTE Pre-assembled modular mechanical and electrical unit
40、s (e.g. heating and cooling modules) may be treated as an assembly of components supported by the modular unit housing structure (see 9.5).1.4 Components excludedThe requirements of this International Standard are not intended for application to furnishings, or temporary or relocatable components (s
41、ee Annex A).With the exception of parapets (as described in Annex A), application of this International Standard to components in buildings subject to low levels of seismic hazard may not be warranted.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in t
