ICC-ES AC552
Full Name
ICC-ES AC552 – Acceptance Criteria for Mechanical Splice Systems for Fiber Reinforced Polymer (FRP) Bars
Scope
ICC-ES AC552 outlines the acceptance criteria for evaluating mechanical splice systems designed for connecting fiber-reinforced polymer (FRP) bars used in concrete structures. These splice systems are crucial for achieving continuous reinforcement and transferring loads between FRP bar segments.
The scope of AC552 encompasses several key aspects:
- Mechanical properties: assessment of the mechanical performance of the splice system, including tensile strength, fatigue resistance, and slip behavior, to ensure it meets the required structural capacity and durability.
- Connection design: evaluation of the design of the splice system, including its geometry, materials, and manufacturing process, to ensure reliable and consistent performance.
- Compatibility with FRP bars: verification of the splice system’s compatibility with different types and sizes of FRP bars, considering factors such as bar diameter, surface texture, and resin type.
- Installation procedures: assessment of the installation procedures for the splice system, including the required tools and techniques, to ensure proper and efficient assembly.
- Code compliance: verification that the splice system and its installation comply with relevant building codes and standards, such as ACI 440.1R.
The evaluation process typically involves a combination of laboratory testing, engineering analysis, and review of manufacturer’s documentation to verify compliance with the acceptance criteria.
