Abstract

This presentation is intended to provide practical insight for practicing New Zealand consulting engineers into what a “C2 capacity” does, and does not, represent, the history of this assessment method, genuine areas of ambiguity, and the application of this value in accordance with NZS3101:2006.
Since the inclusion of references to Eurocode ETAG-001 for the assessment and design of post-installed anchors in concrete in Amendment 3 to NZS 3101:2006, uncertainty has existed not only around the specifics of this testing but what the published "C2 Capacity" represents and its direct applicability to New Zealand codes and standards.
While these specifics are well understood by the comparatively small number of individuals in the anchor industry or academia who have had direct and in-depth exposure to this test regime (less again who are also professionally familiar with NZ codes), many practicing engineers who apply these capacities in their design, by reasonable limitations of time and attention, rarely have the opportunity to gain a depth of understanding into what these values represent.
