Though anchor channels with channel bolts are used in practice since long time, the codification of their design rules was just recently finalized in Europe with the issuing of the new EN 1992‐4. In the United States, full consolidation of the design rules for anchor channels with channel bolts in ACI 318 is yet to be included. The design requires product‐specific design data that are provided in qualification certificates. Qualification is carried out in Europe and in the United States according to published qualification guidelines. Currently, the qualification guidelines and design rules are not fully harmonized between Europe and the United States, sometimes resulting in significantly different design outcomes. This paper describes the framework of qualification and design, provides a comprehensive compendium of all design rules required for anchor channel‐channel bolt‐systems, and points out the differences between Europe and the United States with regard to qualification and design.
