Abstract

This research project investigated the sustained load performance of adhesive anchors in concrete under different installation and in-service conditions. Based on the results of the literature review and the experience of the research group, a triage was conducted on many parameters identified as possibly affecting the sustained load performance of adhesive anchors, and the highest-priority parameters were investigated in this project. A stress versus time-to-failure approach was used to evaluate sensitivity of three ICC-ES AC308 approved adhesive anchor systems. Of the various parameters investigated, only elevated in-service temperature and manufacturer's cure time were shown to exhibit adverse effects on sustained loads more than that predicted by short-term tests of fully cured adhesives.
