(2) The design methods given in EN 1993-1-13 are applicable if:
-   the execution quality is as specified in EN 1090-2, and
-   the construction materials and products used are as specified in the relevant parts of the EN 1993 series, or in the relevant material and product specifications.

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.
The requirements 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 fixture. The requirements for the design of the fixture are given in the appropriate Standards and fulfil the requirements on the fixture as given in this EN.
(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 are given in a European Technical Product Specification for the corresponding loading conditions providing a basis for the design methods of this EN.
NOTE   The numerical values for certain parameters given in Notes can be used for pre-dimensioning. The values for verification are given in the European Technical Product Specifications and may be different.
1.2   Type of fasteners and fastening groups
(1)   This EN uses the fastener design theory ) (see Figure 1.1) and applies to:
a)   cast-in fasteners such as headed fasteners, anchor channels with rigid connection (e.g. welded, forged) between anchor and channel;
b)   post-installed mechanical fasteners such as expansion fasteners, undercut fasteners and concrete screws;
c)   post-installed bonded fasteners and bonded expansion fasteners.
(2)   For other types of fasteners modifications of the design provisions can 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 group of fasteners the loads are applied to the individual fasteners of the group by means of a common fixture. In a group of fasteners this European Standard applies only if fasteners of the same type and size are used.
(5)   The configurations of fastenings with cast-in place headed fasteners and post-installed fasteners covered by this EN are shown in Figure 1.2.
(6)   For anchor channels the number of anchors is not limited.
(...)
(7)   Post-installed ribbed reinforcing bars used to connect concrete members are covered by a European Technical Product Specification. This EN applies when connections are designed in accordance with EN 1992-1-1.
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. (....)

This Technical Report gives provisions for design of ultimate limit states in addition to EN 1992 4 for headed and post-installed fasteners excluding concrete screws, which only transmit static actions to the concrete, when the loads on individual fasteners are determined according to plastic analysis of the joint where only equilibrium conditions but no compatibility conditions are considered. Fatigue, impact and seismic loads are not covered.

EN 1992-4:2018 covers anchor channels located in cracked or uncracked concrete subjected to tensile loads and/or shear loads transverse to the longitudinal channel axis as well as combinations of these loads. Shear loads acting in direction of the longitudinal axis of the channel and combinations of shear loads acting transverse and in direction of the longitudinal axis of the channel, combinations of tensile loads and shear loads acting in direction of the longitudinal axis of the channel and combinations of loads in all three directions are excluded.
This Technical Report provides design rules for anchor channels under static and quasi-static shear loads acting in direction of the longitudinal channel axis and all possible combinations of shear and tension loads acting on the channel as well as design rules for anchor channels with supplementary reinforcement to take up shear loads, additional and alternative to the provisions of EN 1992- 4:2018. All relevant failure modes are considered and will be verified. Fatigue, impact and seismic loads are not covered.
The design rules in this document are only valid for anchor channels with a European Technical Product Specification. The design provisions for shear loads acting in direction of the longitudinal axis of the channel cover the following anchor channels and applications:
-   Anchor channels with 2 or 3 anchors.
-   Anchor channels where the shear load in the longitudinal axis of the channel is transferred to the channel by corresponding locking channel bolts creating mechanical interlock by means of a notch in the channel lips or serrated channel bolts which interlock with serrated lips of the channel (Figure 1).
-   Anchor channels produced from steel with at least two metal anchors rigidly connected to the back of the channel (e.g. by welding, forging or screwing). The anchor channels are placed flush with the concrete surface. A fixture is connected to the anchor channel by channel bolts with nut and washer.
-   Anchor channels close to the edge placed either parallel or transverse to the edge of the concrete member. The design provisions for concrete edge failure do not cover channel orientations inclined to the concrete edge.
The design method for anchor channels loaded in shear in direction of the longitudinal axis of the channel follows closely the existing design model for headed fasteners. For reasons of simplicity modifications specific for anchor channels are used where necessary.
The design provisions for the supplementary reinforcement to take up shear loads in case of anchor channels situated parallel to the edge and loaded in shear transverse to the longitudinal axis apply to anchor channels with unlimited number of anchors.
Examples of anchor channels and channel bolts ensuring mechanical interlock are given in Figure 1.

1.1   General
This Technical Report provides design rules for fasteners used to connect statically indeterminate non-structural light weight systems (e.g. suspended ceilings, pipe work, ducting) to concrete members such as walls or floors (see Figure 1)).
The proposed design model may be applied to post-installed mechanical and bonded anchors covered by EN 1992-4:2017, 1.2. Their suitability will be confirmed in a European Technical Product Specification.
The design rules assume the following:
-   under extreme conditions (e.g. large crack width) excessive slip or failure of a fastener might occur;
-   elements or systems are attached with at least three fixing points with one or more fasteners at each fixing point;
-   where more than one fastener is used at a fixing point (MF, see Figure 1), only fasteners of the same type, size and length are used;
-   the attached system is sufficiently stiff to transfer the load at any fixing point to adjacent fixing points without significantly impairing the performance characteristics of the system both at serviceability and ultimate limit states.
(...)
This Technical Report applies to non-structural applications in structures covered by EN 1992-1-1. In applications where special considerations apply, e.g. nuclear power plants or civil defence structures, modifications may be necessary.
This document does not cover the design of the fixture. The design of the fixture will be carried out to comply with the appropriate Standards.
1.2   Type of fasteners
Post-installed fasteners according to EN 1992-4.
1.3   Fastener dimensions and materials
EN 1992-4:2017, 1.3 applies with the following addition: In precast pre-stressed hollow core elements the minimum embedment depth may be reduced to a value to ensure proper functioning if placed in a flange (wall) of minimum thickness of 17 mm. In this case the minimum embedment depth and the admissible position of the fastener in the hollow core slab given in the relevant European Technical Product Specification will be observed (Figure 2).
(...)-
1.4   Fastener loading
Loading on the fastenings will only be quasi static. Fatigue, impact and seismic loads are not covered.
Any axial compression on the fixture will be transmitted to the concrete either without acting on the fastener or via fasteners suitable for resisting compression.
1.5   Concrete strength
EN 1992-4 applies.
1.6   Concrete member loading
EN 1992-4 applies. However, fatigue, impact and seismic loads are not covered.
1.7   Concrete member dimensions
The minimum thickness of members in which fasteners are installed is at least 80 mm unless otherwise specified in the European Technical Product Specification. For precast pre-stressed hollow core elements, the minimum wall thickness is 17 mm.
