Experimental Bond Characterisation and Inverse Numerical Stress-Slip Law Identification for Adhesive Anchor Applications

Popis výsledku v původním jazyce

In order to determine the adhesive anchors' capacity under tensile loading, two test methods (confined and unconfined) are suggested in the guideline. Improvements for one of the two configurations are proposed and tested in this paper. The alternative setup currently being evaluated is a modified version of the one proposed by the RILEM technical recommendation, which is used to determine the bond properties of reinforced concrete elements. Finding a better and more consistent definition of the bonded length, removing the concrete surface contribution from the determined bond resistance, and testing the stability improvements were considered during the proposed setup development. In order to describe the adhesive anchor system's behaviour, a stress-slip relation (law), which relates the local axial bond stress to the local axial slippage, can be used. Analytical and numerical procedures have been proposed in the literature in order to determine such a law. Here, an inverse calibration method based on Sequentially Linear Analysis (SLA) is applied in order to identify the stress-slip law of pull-out tests.
