摘要：hemical anchorages are applied in many engineering implementations, particularly strengthening ofreinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, sincethey 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 thiscontext; the most important experiment is to determine the pull-out loads of embedded anchoragereinforcement by applying axial loads. In this study; it is aimed to determine the displacements of steelreinforcements, embedded into concrete by using chemical anchorages, while applying axial pulling loads. Inorder to determine the displacements and load - deformation graphs; starting conditions and every 10 barpressure applied conditions of the steel reinforcements were captured by the cameras. The obtained imageswere evaluated by using photogrammetric software. Based on the photogrammetric post-processing results, theload - deformation graphs were plotted and the loads at loss of adhesion were determined.
