Abstract: Post-installed reinforcing bars are getting increasingly popular to connect new to existing reinforced concrete structures. For this, reinforcing bars are bonded to the hardened concrete by means of adhesives which are basically two-component chemicals filled in injectable cartridges. Various qualification guidelines and design codes form the regulative basis for all approved products in Europe and the USA. These regulations are largely harmonized in both regions. However, there are also some differences in detail aspects e.g. in regard to seismic and fire design. This paper introduces the context of post-installed rebar anchoring systems. An overview of relevant international regulations for design and qualification will be provided, and specific requirements of European and US regulations are highlighted. The differences between post-installed anchor and post-installed rebar applications are briefly discussed and the latest developments in techniques and applications outlined. The contribution aims at bringing the technique of post-installed reinforcing bars to the attention of a broader audience of the engineering and research community.
