Abstract:
International efforts to harmonize the testing, qualification and design of post-installed anchors have resulted in closely aligned standards / guidelines in Europe and the U.S. The implementation of ETAG 001, Part 5 (EOTA 1997) in the E.U. and AC308 (ICC-ES 2006) in the U.S. represents a major new step in the harmonization efforts and has resulted in nearly parallel approaches in the two regions with regards to the qualification and design of adhesive anchors. Nevertheless, while the standards alignment permits portability of test data from one system to the other, significant differences remain between the two systems. In addition, efforts to adopt AC308 into the building code for structural concrete in the U.S. (ACI Committee 355 2008) have resulted in further dissimilarities. This paper focuses on the similarities and differences between the European and American qualification systems for adhesive anchor products. An insight into the issuance of Evaluation Reports and Technical Approvals is provided. Information regarding manufacturing and quality control requirements imposed as a part of the product qualification is included. A brief review of the design procedures adopted in ETAG 001 and in AC308 is provided. The current status of the ACI 355.X standard which is currently under development is also discussed, and regional differences in job-side quality control and installation inspection are discussed.
