Eurocode 2 - Design of concrete structures - Part 4: Design of fastenings for use in concrete
1.1 General
(1) This EN provides a design method for fastenings (connection of structural elements and non-structural elements to structural components), which are used to transmit actions to the concrete.
Inserts embedded in precast concrete elements during production, under Factory Production Control (FPC) conditions and with the due reinforcement, intended 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.
(2) This EN is intended for safety related applications in which the failure of fastenings will result in collapse or partial collapse of the structure, cause risk to human life or lead to significant economic loss. In this context it also covers non-structural elements.
(3) The support of the fixture may be either statically determinate or statically indeterminate. Each support may consist of one fastener or a group of fasteners.
(4) This EN 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. The transmission of the fastener loads to the supports of the concrete member shall be shown for the ultimate limit state and the serviceability limit state according to EN 1992-1-1.
(5) This EN does not cover the design of the fixture. The design of the fixture shall be carried out to comply with the appropriate Standards.
(6) This document relies on characteristic resistances and distances which are stated in a European Technical Product Specification (see Annex E). At least the characteristics of Annex E, Table E.1 should be given in a European Technical Product Specification providing a basis for the design methods of this EN.
1.2 Type of fasteners and fastening groups
(1) This EN uses the fastener design theory ) (Figure 1.1) and applies to:
a) cast-in fasteners such as headed fasteners, anchor channels with rigid connection between anchor and channel;
b) post-installed mechanical fasteners such as expansion anchors, undercut anchors and concrete screws;
c) post-installed bonded anchors, bonded expansion anchors and bonded undercut anchors.
NOTE Connections with post-installed ribbed reinforcing bars should be covered by a European Technical Product Specification and comply with the requirements of EN 1992-1-1.
(2) For other types of fasteners modifications of the design provisions may be necessary.
(3) This EN applies to fasteners with established suitability for the specified application in concrete covered by provisions, which refer to this EN and provide data required by this EN. The suitability of the fastener is stated in the relevant European Technical Product Specification.
(...)
(4) This EN applies to single fasteners and groups of fasteners. In a fastening group the loads are applied to the individual fasteners of the group by means of a common fixture. In this EN it is assumed that in a fastener group only fasteners of the same type and size are used.
The configurations of fastenings with cast-in place headed fasteners and post-installed fasteners covered by this EN are shown in Figure 1.2.
For anchor channels the number of fasteners is not limited.
(...)
NOTE Configuration with three fasteners is not recommended close to an edge (ci < 100mm) as there are no safe design models for shear loads.
1.3 Fastener dimensions and materials
(1) This EN applies to fasteners with a minimum diameter or a minimum thread size of 6 mm (M6) or a corresponding cross section. In general, the effective embedment depth should be: hef 40 mm. The actual value for a particular fastener shall be taken from the relevant European Technical Product Specification. In case of post-installed chemical fasteners the effective embedment depth is limited to hef 20dnom. (....)

Evrokod 2 - Projektiranje betonskih konstrukcij - 4. del: Projektiranje pritrjevanja za uporabo v betonu
1.1 Splošno
(1) Ta standard EN določa metodo projektiranja za pritrjevanje (povezovanje konstrukcijskih elementov in nekonstrukcijskih elementov v konstrukcijske komponente), ki se uporablja za povezovanje z betonom.
Vložke, vstavljene v montažne betonske elemente med proizvodnjo, v pogojih tovarniške kontrole proizvodnje (FCP) in z ustrezno ojačitvijo, namenjene za uporabo samo v prehodnih obdobjih za dvigovanje in rokovanje, obravnava CEN/TR »Projektiranje in uporaba vložkov za dvigovanje montažnih betonskih elementov ter rokovanje z njimi«, in sicer CEN/TC 229.
(2) Ta standard EN je namenjen za uporabo, povezano z varnostjo, pri katerih bi odpoved pritrjevanja povzročila zrušitev ali delno zrušitev konstrukcije ter s tem pomenila nevarnost za življenja ljudi ali privedla do velike gospodarske škode. V tem kontekstu obravnava tudi nekonstrukcijske elemente.
(3) Podpora pritrditve je lahko statično določena ali statično nedoločena. Vsaka podpora lahko zajema eno vezno sredstvo ali skupino veznih sredstev.
(4) Ta standard EN je veljaven za načine uporabe, ki spadajo na področje uporabe skupine standardov EN 1992. Pri načinih uporabe, kjer veljajo posebne zahteve, npr. pri jedrskih elektrarnah ali zgradbah civilne obrambe, so morda potrebne prilagoditve. Opraviti je treba prenos obremenitev pritrjevanja na nosilce betonskih elementov za prikaz skrajnega mejnega stanja in mejnega stanja uporabnosti v skladu s standardom EN 1992-1-1.
(5) Ta standard EN ne obravnava projektiranja pritrditve. Projektiranje pritrditve se izvede v skladu z ustreznimi standardi.
(6) Ta dokument temelji na značilnih odpornostih in razdaljah, ki so navedene v evropski tehnični specifikaciji za izdelke (glej dodatek E). V evropski tehnični specifikaciji za izdelke je treba navesti vsaj značilnosti iz dodatka E, preglednica E.1, kar zagotavlja podlago za metode projektiranja iz tega standarda EN.
1.2 Vrste veznih sredstev in skupin veznih sredstev
(1) Ta standard EN uporablja teorijo projektiranja veznih sredstev (slika 1.1) in se uporablja za:
a) ulita vezna sredstva, kot so vezna sredstva z glavo, odprti profili za sidranje s togo povezavo med sidrom in kanalom;
b) naknadno vgrajena mehanska vezna sredstva, kot so ekspanzijska sidra, spodrezana sidra in betonski vijaki;
c) naknadno vgrajena vezana sidra, vezana ekspanzijska sidra in vezana spodrezana sidra.
OPOMBA: Povezave z naknadno vgrajenimi rebrastimi ojačitvenimi drogovi morajo biti vključene v evropski tehnični specifikaciji za izdelke in ustrezati zahtevam standarda EN 1992-1-1.
(2) Za druge vrste veznih sredstev so morda potrebne spremembe določb projektiranja.
(3) Ta standard EN se uporablja za vezna sredstva z ugotovljeno primernostjo za določen namen uporabe v betonu v skladu z določbami, ki se nanašajo na ta standard EN in zagotavljajo podatke, ki jih zahteva ta standard EN. Primernost veznega sredstva je navedena v ustrezni evropski tehnični specifikaciji za izdelke.
(...)
(4) Ta standard EN se uporablja za posamezna vezna sredstva in skupine veznih sredstev. V skupini veznih sredstev obremenitve veljajo za posamezna vezna sredstva v skupini s skupno pritrditvijo. V tem standardu EN se domneva, da so v skupini veznih sredstev uporabljena samo vezna sredstva iste vrste in velikosti.
Konfiguracije veznih sredstev z veznimi sredstvi z glavo, ulitimi na mesto, in naknadno vgrajenimi veznimi sredstvi, ki jih obravnava ta standard EN, so prikazane na sliki 1.2.
Pri odprtih profilih za sidranje število veznih sredstev ni omejeno.

1 Scope
1.1 General
(1) This European Standard provides a design method for fastenings (connection of structural elements
and non-structural elements to structural components), which are used to transmit actions to the
concrete. This design method uses physical models which are based on a combination of tests and
numerical analysis consistent with EN 1990:2002, 5.2.
Additional rules for the transmission of the fastener loads within the concrete member to its supports
are given in EN 1992-1-1 and Annex A of this EN.
Inserts embedded in precast concrete elements during production, under Factory Production Control
(FPC) conditions and with the due reinforcement, intended for use only during transient situations for
lifting and handling, are covered by CEN/TR 15728.
(2) This EN is intended for safety related applications in which the failure of fastenings may result in
collapse or partial collapse of the structure, cause risk to human life or lead to significant economic loss.
In this context it also covers non-structural elements.
(3) The support of the fixture can be either statically determinate or statically indeterminate. Each
support can consist of one fastener or a group of fasteners.
(4) This EN is valid for applications which fall within the scope of the EN 1992 series. In applications
where special considerations apply, e.g. nuclear power plants or civil defence structures, modifications
can be necessary.
(5) This EN does not cover the design of the fixtu

1 Scope
1.1 General
(1) This EN provides a design method for fastenings (connection of structural elements and non-structural
elements to structural components), which are used to transmit actions to the concrete.
Inserts embedded in precast concrete elements during production, under Factory Production Control (FPC)
conditions and with the due reinforcement, intended 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.
(2) This EN is intended for safety related applications in which the failure of fastenings will result in collapse
or partial collapse of the structure, cause risk to human life or lead to significant economic loss. In this context
it also covers non-structural elements.
(3) The support of the fixture may be either statically determinate or statically indeterminate. Each support
may consist of one fastener or a group of fasteners.
(4) This EN 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. The transmission of the fastener loads to the supports of the concrete member shall be shown for
the ultimate limit state and the serviceability limit state according to EN 1992-1-1.
(5) This EN does not cover the design of the fixture. The design of the fixture shall be carried out to comply
with the appropriate Standards.
(6) This document relies on characteristic resistances and distances which are stated in a European
Technical Product Specification (see Annex E). At least the characteristics of Annex E, Table E.1 should be
given in a European Technical Product Specification providing a basis for the design methods of this EN.
1.2 Type of fasteners and fastening groups
1)
(1) This EN uses the fastener design theory (Figure 1.1) and applies to:
a) cast-in fasteners such as headed fasteners, anchor channels with rigid connection between anchor and
channel;
b) post-installed mechanical fasteners such as expansion anchors, undercut anchors and concrete screws;
c) post-installed bonded anchors, bonded expansion anchors and bonded undercut anchors.
NOTE Connections with post-installed ribbed reinforcing bars should be covered by a European Technical Product
Specification and comply with the requirements of EN 1992-1-1.
(2) For other types of fasteners modifications of the design provisions may be necessary.
(3) This EN applies to fasteners with established suitability for the specified application in concrete covered
by provisions, which refer to this EN and provide data required by this EN. The suitability of the fastener is
stated in the relevant European Technical Product Specification.
1)
In fastener design theory the concrete tensile capacity is directly used to transfer loads into the concrete component.

(4) This EN applies to single fasteners and groups of fasteners. In a fastening group the loads are applied to
the individual fasteners of the group by means of a common fixture. In this EN it is assumed that in a fastener
group only fasteners of the same type and size are used.
The configurations of fastenings with cast-in place headed fasteners and post-installed fasteners covered by
this EN are shown in Figure 1.2.
For anchor channels the number of fasteners is not limited.

Figure 1.2 — Configuration of headed and post-installed fastenings covered by this EN
NOTE Configuration with three fasteners is not recommended close to an edge (c < 100mm) as there are no safe
i
design models for shear loads.
1.3 Fastener dimensions and materials
(1) This EN applies to fasteners with a minimum diameter or a minimum thread size of 6 mm (M6) or a
corresponding cross section. In general, the effective embedment depth should be: h ≥ 40 mm. The actual
ef
value for a particular fastener shall be taken from the relevant European Technical Product Specification. In
case of post-installed chemical fasteners the effective embedment depth is limited to h ≤ 20dnom. In case of
ef
fasteners for multiple use for non-structural applications as addressed in 7.3 the minimum thread size is 5 mm
(M5) and the effective embedment depth shall be at least 30 mm, which in special cases (internal exposure
conditions only) can be reduced to 25 mm.
(2) This EN covers metal fasteners made of either carbon steel (ISO 898, EN 10025, EN 10080), stainless
steel (EN 10088, ISO 3506) or malleable cast iron (ISO 5922). The surface of the steel may be coated or
uncoated. This EN is valid for fasteners with a nominal steel tensile strength f ≤ 1000 N/mm². This strength
uk
limit does not apply to concrete screws. The binding material of bonded fasteners may be made primarily of
resin, cement or a combination of the two. In addition inorganic fillers may be used.

prEN 1992-4:2013 (E)
1.4 Fastener loading
(1) Loading on the fastenings may be static, quasi-static, fatigue, impact and seismic. The suitability of the
fastener to resist fatigue, impact and seismic loadings is specifically stated in the relevant European Technical
Product Specification. Anchor channels subjected to fatigue loading or seismic loading are not covered by this
EN.
NOTE Design rules for anchor channels subjected to fatigue loading or seismic loading may be found in the
CEN/TR "Anchor channels" which is under preparation.
(2) The loading on the fastener resulting from the actions on the fixture (e.g. tension, shear, bending or
torsion moments or any combination thereof) will generally be axial tension and/or shear. When the shear
force is applied with a lever arm a bending moment on the fastener will arise. Any axial compression on the
fixture should be transmitted to the concrete either without acting on the fastener or via fasteners suitable for
resisting compression.
(3) In case of anchor channels shear in the direction of the longitudinal axis of the channel is not covered by
this EN.
NOTE Design rules for anchor channels with loads acting in the direction of the longitudinal axis of the anchor
channel may be found in the CEN/TR "Anchor channels" which is under preparation.
1.5 Concrete strength
(1) This EN is valid for fasteners installed in members using normal weight concrete with strength classes in
the range C12/15 to C90/105 all in accordance with EN 206-1. However in the design of fastenings the
strength class is limited to C60/75 even if the structure uses a higher strength class. The range of concrete
strength classes in which particular fasteners may be used is given in the relevant European Technical
Product Specification and may be more restrictive than stated above.
1.6 Concrete member loading
(1) In general fasteners are prequalified for applications in concrete members under static loading. If the
concrete member is subjected to fatigue or seismic loading, prequalification of the fastener specific to this type
of loading and a corresponding European Technical Product Specification are required.
