Abstract

hemical anchorages are applied in many engineering implementations, particularly strengthening of
reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, since
they supply to transfer the load between existing construction elements and newly added elements. Therefore;
the study of the quality of chemical anchorages is an important issue in construction materials science. In this
context; the most important experiment is to determine the pull-out loads of embedded anchorage
reinforcement by applying axial loads. In this study; it is aimed to determine the displacements of steel
reinforcements, embedded into concrete by using chemical anchorages, while applying axial pulling loads. In
order to determine the displacements and load - deformation graphs; starting conditions and every 10 bar
pressure applied conditions of the steel reinforcements were captured by the cameras. The obtained images
were evaluated by using photogrammetric software. Based on the photogrammetric post-processing results, the
load - deformation graphs were plotted and the loads at loss of adhesion were determined.
