Generally, post installed anchors are required to attach equipment to concrete structures. In addition, a mechanical anchor that can perform infrastructure maintenance management and preventive maintenance during the operation period is required. In this study, we developed a post installed anchor that can be maintained. In addition, we tested its anchor tensile performance. In the construction method, a tensile load was applied and the load was released in order to integrate the anchor extension with concrete. In the following, I conduct a tensile performance test, and report the results confirmed for tensile stiffness, tensile strength, and fracture mode.
