PAEZ-MORENO, Diego Fernando  and  HAMON-CAICEDO, Jeniffer. Study of Tensile Strength in Structural Anchors Post-Installed with Epoxy Adhesive. Rev. ing. univ. Medellín [online]. 2018, vol.17, n.33, pp.57-70. ISSN 1692-3324.  https://doi.org/10.22395/rium.v17n33a3.

Research carried out on post-installed structural anchors has shown a link between the embedded length and the diameter of the bore with maximum tensile strength. This paper, is the outcome of research funded by the research department of the Universidad Pedagógica y Tecnológica de Colombia, analyzes this link from the variation of resistance and failure type in structural anchor prototypes with variations in embedded length and drilling diameter, in particular compressive strength 28 MPa, epoxy adhesive, reinforcing bar, 15 graphite units of 0.007 m diameter, and 15 corrugated steel units of 0.0095 m diameter, for a total of 30 systems requested for direct traction in the universal machine. The results showed that tensile strength and failure type are a function of the embedded length and corrugated structure of the anchored reinforcing bar.

Keywords : epoxy resin; adhesive anchors; strength.
