Design Issues for Axially Loaded Anchors in Strengthening Applications

Abstract

Over the past few decades, due to the developments of chemical adhesives, usage of anchorages is spread out in strengthening applications. Anchorages have a vital role to ensure those applications accurate. In case of misapplications, connection between existing structural member and added one may not transfer required forces which means non-efficient retrofitting. Therefore, a number of recommendations are done regarding free-edge distance and embedment depth of axially loaded anchors embedded to both low and normal strength concrete. Furthermore, experimental results are compared with ACI-318 Appendix D recommendations.
