Tensile behavior of newly developed undercut anchor in cracked and uncracked concrete

The authors have been designing a post-installed anchor that fixes itself into concrete material by expanding the tip in an upward direction, and conducted tensile loading tests to confirm its fundamental dynamic characteristics. test results on three types of specimens, with morphology as parameter, indicate final failure modes were all bar fractures, stable yield strength was confirmed. Additionally, characteristics proposed cases where cracks are present surface, wherein anchors fixed, experimentally
