Mechanics of an Adhesive Anchor System Subjected to a Pullout Load. I: Elastic Analysis
Publication: Journal of Structural Engineering
Volume 140, Issue 2
Abstract
An elastic solution is developed for an anchor embedded in a concrete hole and bonded to the concrete through an adhesive layer that is not necessarily thin. Both bonded and debonded conditions are considered for the embedded end of the anchor. A weak-form stress boundary condition yields an approximate solution for the elastic fields in both the anchor core and the adhesive layer, which compares favorably with an axisymmetric finite-element solution. The explicit elastic solution is useful as a more complete design basis for such anchors but also provides a platform for the analysis of the long term response of bonded anchors when time-dependent effects are observed. Paper II pursues that analysis.
