Attention is drawn to the possibility that some of the elem

24、ents of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This Technical Specification CEN/TS 1992-4-1 General, describes the general principles and requirements for safety, serviceability and durability

25、 of fasteners for use in concrete, together with specific requirements for structures serving as base material for the fasteners. It is based on the limit state concept used in conjunction with a partial factor method. The numerical values for partial factors and other reliability parameters are rec

26、ommended values and may be changed in a National Annex, if required. The recommended values apply when: a) the fasteners comply with the requirements of 1.2.2, and b) the installation complies with the requirements of 4.5. CEN/TS 1992-4 Design of fastenings for use in concrete is subdivided into the

27、 following parts: Part 1: General Part 2: Headed fasteners Part 3: Anchor channels Part 4: Post-installed fasteners Mechanical systems Part 5: Post-installed fasteners Chemical systems Part 1 is applicable to all products. Special rules applicable to particular products are given in Parts 2 to 5 of

28、the series CEN/TS 1992-4. These Parts should be used only in conjunction with Part 1. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Cyprus, Czech Repub

29、lic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. National Annex for CEN/TS 1992-4-1 This CEN/TS gives

30、 values with notes indicating where national choices may have to be made. When this CEN/TS is made available at national level it may be followed by a National Annex containing all Nationally Determined Parameters to be used for the design of fastenings according to this CEN/TS for use in the releva

31、nt country. National choice of the partial factors and reliability parameters is allowed in design according to this CEN/TS in the following clauses: 4.4.2; 4.4.3.1.1; DD CEN/TS 1992-4-1:2009CEN/TS 1992-4-1:2009 (E) 5 4.4.3.1.2; 4.4.3.1.3; 4.4.3.2; 4.4.3.3; 5.1.2; B.3.1; D.2.

32、CEN/TS 1992-4-1:2009 (E) 6 1 Scope 1.1 General 1.1.1 This CEN/TS provides a design method for fasteners for structural purposes, which are used to transmit actions to the concrete. Inserts embedded in precast concrete elements during production, under FPC conditions and with the due reinforcement, i

33、ntended for use only during transient situations for lifting and handling, are covered by the CEN/TR “Design and Use of Inserts for Lifting and Handling Precast Concrete Elements”, by CEN TC 229. 1.1.2 This CEN/TS is intended for applications in which the failure of fastenings will: 1) result in col

34、lapse or partial collapse of the structure, or 2) cause risk to human life, or 3) lead to significant economic loss. 1.1.3 The support of the fixture may be either statically determinate or statically indeterminate, defined as multiple anchor use in some European Technical Approvals (ETAs). Each sup

35、port may consist of one fastener or a group of fasteners. 1.1.4 This CEN/TS is valid for applications which fall within the scope of the series EN 1992. In applications where special considerations apply, e.g. nuclear power plants or civil defence structures, modifications may be necessary. 1.1.5 Th

36、is CEN/TS does not cover the design of the fixture. The design of the fixture shall be carried out to comply with the appropriate Standards. Requirements for stiffness and ductility of the fixture are given in clauses 5 and 8. 1.2 Type of fasteners and fastening groups 1.2.1 This CEN/TS applies to:

37、a) cast-in fasteners such as headed fasteners, anchor channels with rigid connection between fastener and channel; b) post-installed anchors such as expansion anchors, undercut anchors, concrete screws, bonded anchors, bonded expansion anchors and bonded undercut anchors. For other types of fastener

38、s modifications of the design provisions may be necessary. 1.2.2 This CEN/TS applies to fasteners with established suitability for the specified application in concrete covered by provisions, which refer to this CEN/TS and provide data required by this CEN/TS. The necessary data are listed in Parts

39、2 to 5. NOTE Where there is no European Standard for a particular fastener which refers specifically to the use of this fastener or where the fastener deviates significantly from the European Standard, the establishment of suitability may result from: a) European Technical Approval (ETA) which refer

40、s specifically to the use of the fastener in concrete; b) relevant national standard or provision which refers specifically to the use of the fastener in concrete; c) documentation of the fastener should include the characteristic resistance of the fastener and consider effects influencing the relia

41、bility of fasteners both during installation and in service life under sustained and variable loads, as well as the sensitivity to possible deviations on any of the factors of importance. DD CEN/TS 1992-4-1:2009CEN/TS 1992-4-1:2009 (E) 7 d) Factors to be addressed are: 1) Installation conditions in

42、concrete on site. 2) Drilling method and drill bit diameter in case of post-installed fasteners. 3) Bore hole cleaning. 4) Installation tools. 5) Sustained (long term) and variable loads on the fastener. 6) Variable loads on the concrete structure (crack cycling). 7) Crack width in the concrete stru

43、cture. 8) Environmental conditions such as air pollution, alkalinity, aggressive environment, humidity, concrete- installation temperature, service temperature 9) Location of fasteners in the concrete component. 10) Minimum dimensions of the structural component. In addition to the assumptions of EN

44、 1992-1-1 it is assumed that both the design and execution of fastening systems in concrete structures is carried out by personnel having the appropriate skill and experience. 1.2.3 This CEN/TS applies to single fasteners and groups of fasteners. In a fastening group the loads are applied to the ind

45、ividual fasteners of the group by means of a common fixture. In this CEN/TS it is assumed that in a fastening group only fasteners of the same type and size are used. The configurations of fasteners (cast-in place headed fasteners and post-installed fasteners) covered by this CEN/TS are shown in Fig

46、ure 1. Distinction is to be made between fastenings with and without hole clearance. The following applications may be considered to have no hole clearance: a) bolts are welded to the fixture or screwed into the fixture, or b) any gap between the fastener and the fixture is filled with mortar of suf

47、ficient compression strength or eliminated by other suitable means; For anchor channels the number of fasteners is not limited.
