Yayın Determining pull-out deformations by means of an online photogrammetry monitoring system(Cem Gazioğlu, 2015-03-02) Avşar, Emin Özgür; Altan, Mehmet Orhan; Doğan, Ünal Anıl; Akça, DevrimChemical 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.Yayın Determining pull - out deformations of bonded metal anchors embedded in concrete by means of photogrammetry(International Society for Photogrammetry and Remote Sensing, 2012) Avşar, Edip Özgür; Altan, Mehmet Orhan; Doğan, Umut Anıl; Akça, Mehmet DevrimChemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures.
