General

This Technical Report provides design rules for fasteners used to connect statically indeterminate nonstructural 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 is given 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.
