24、without license from IHS -,-,- ISO 22762-3:2005(E) ISO 2005 All rights reserved v 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 throug
25、h ISO technical 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 collaborat
26、es closely with the International 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 Standard
27、s. Draft International Standards 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 thi
28、s document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22762-3 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses). ISO 22762 consists of the following
29、parts, under the general title Elastomeric seismic-protection isolators: Part 1: Test methods Part 2: Applications for bridges Specifications Part 3: Applications for buildings Specifications Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=IHS

31、rs one for bridges and the other for buildings since the requirements for isolators for bridges and for buildings are quite different, although the basic concept of the two products is similar. Therefore, when this International Standard is applied to the design of bridge isolators, Part 2 and the r
32、elevant clauses in Part 1 are used and, when it is applied to building isolators, Part 3 and the relevant clauses in Part 1 are used. The main differences to be noted between isolators for bridges and isolators for buildings are as below: a) Isolators for bridges are mainly rectangular in shape and
33、those for buildings circular in shape. b) Isolators for bridges are designed to be used for both rotation and horizontal displacement, while isolators for buildings are designed for horizontal displacement only. c) Isolators for bridges are designed to perform on a daily basis to accommodate length
34、changes of bridges caused by temperature changes as well as during earthquakes, while isolators for buildings are designed to perform only during earthquakes. d) Isolators for bridges are designed to withstand dynamic loads caused by vehicles on a daily basis as well as earthquakes, while isolators
35、for buildings are mainly designed to withstand dynamic loads caused by earthquakes only. For structures that are neither buildings nor bridges (e.g. tanks), the structural engineer may use either Part 2 or Part 3 of this International Standard, depending on the requirements of the structure.

37、005 All rights reserved 1 Elastomeric seismic-protection isolators Part 3: Applications for buildings Specifications 1 Scope ISO 22762 applies to elastomeric seismic isolators used to provide buildings or bridges with protection from earthquake damage. The isolators covered consist of alternate elas
38、tomer layers and reinforcing steel plates. They are placed between a superstructure and its substructure to provide both flexibility for decoupling structural systems from ground motion, and damping capability to reduce displacement at the isolation interface and the transmission of energy from the
39、ground into the structure at the isolation frequency. This part of ISO 22762 specifies the requirements for elastomeric seismic isolators used for buildings and the requirements for the rubber material used in the manufacture of such isolators. The specification covers requirements, design rules, ma
40、nufacturing tolerances, marking and labelling and test methods for elastomeric isolators. Some items of classification and some requirements need to be confirmed before production and these should be reviewed using the list given in Annex B. 2 Normative references The following referenced documents
41、are indispensable for the application of this document. For dated references, only the edition cited applies.
