Original Abstract

Post-installed adhesive anchors play an important role in modern construction. As with many structural products, adhesive anchors must undergo rigorous testing to verify serviceability and ultimate performance characteristics under job-site-relevant conditions before being used in real projects. The check of long-term performance under sustained load is based on extrapolation from experimental short-term creep data approximating the creep mechanism of the entire anchor system with a power law model as detailed, for example, in ACI 355.4 and ETAG 001. These normative guidelines are critically reviewed from a scientific as well as practical point of view. Based on the presented evidence, specific recommendations for anchor testing and assessment guidelines are proposed.
