Abstract
In researches done on chemical anchors, also known as post installed structural anchors, they have shown a link between embedded depth and diameter of drilling with maximum resistance to traction. The present article shows the results of an investigation that analyzed the link from the traction resistance variation and type of failure in prototypes of structural anchors with changes in the embedded depth and drilling diameter. The prototypes were made in concrete with different compressive strengths, epoxy adhesive, and various types of reinforcement bars, subjected to pure tensile in universal machine. The results showed that tensile strength and type of failure are on function of a greater embedded depth and the diameter of the reinforcement bar anchored.
