ICC-ES AC557 – Acceptance Criteria for Fiber-reinforced Polymer (FRP) Anchors for Externally Bonded FRP Composite Strengthening Systems for ConcreteScope
ICC-ES AC557 outlines the acceptance criteria for evaluating fiber-reinforced polymer (FRP) anchors used in externally bonded FRP composite strengthening systems for concrete structures. These systems are designed to enhance the strength, durability, and seismic performance of existing concrete members. The scope of AC557 includes:- Material properties: it specifies the requirements for the materials used in FRP anchors and the adhesive systems, including their mechanical properties, durability, and compatibility with concrete.
- Design and installation: it outlines the design criteria for FRP anchor systems, considering factors such as anchor type, size, spacing, embedment depth, and load capacity. It also provides guidelines for proper installation procedures to ensure adequate bond strength and performance.
- Testing: it details the specific tests required to evaluate the performance of FRP anchors under various loading conditions, including tensile, shear, and combined loading tests. It also covers environmental conditioning and durability testing to assess the long-term performance of the anchors.
- Evaluation and certification: it provides a framework for evaluating and certifying FRP anchor systems to ensure they comply with the acceptance criteria and can be safely used in concrete strengthening applications.
