General
This standard piled for post-installed anchoring technology ensuring reliable, safe and economical designs, construction and operation.
This standard applies to the use of post-installed anchoring system in normal weight concrete. It does not cover anchorage to masonry and lightweight/gas concrete.
Anchor design should be based on application (structural elements or non-structural elements), load (tension, compression, moment, shear bined tension pression), action and safety level (important or normal), etc.
The design, installation and acceptance of post-installed anchoring systems ply with this standard and relevant mandatory requirement of current national codes.
In general, this standard is intended to address assessment and design of adhesive anchoring systems where anchor theory applies (see Fig. below). It is not intended to address the assessment and design of post-installed reinforcing bars proportioned according to the concept of reinforcement development (see Fig. below).
Reinforcement designed according to anchor theory (covered in this standard).
Reinforcement designed according to rebar theory (not covered in this standard).
