Full Name

ICC-ES AC454 – Acceptance Criteria for Fiber-reinforced Polymer (FRP) Bars for Internal Reinforcement of Concrete Members

Scope

ICC-ES AC454 provides the acceptance criteria for evaluating fiber-reinforced polymer (FRP) bars used as internal reinforcement in concrete members. It aims to establish guidelines and requirements for these alternative reinforcements where traditional building codes lack specific provisions. The scope of AC454 encompasses:
  • Material properties: it specifies the requirements for the physical and mechanical properties of FRP bars, including tensile strength, modulus of elasticity, and durability under various environmental conditions.
  • Testing: it details the standardized test methods for evaluating the performance of FRP bars under different loading conditions, such as tension, compression, and bending.
  • Design: it outlines the design procedures for using FRP bars as internal reinforcement in concrete members, considering factors like bond strength, anchorage, and serviceability limits.
  • Evaluation: it provides a framework for evaluating FRP bar products to ensure they meet the acceptance criteria and can be safely used as alternatives to steel reinforcement in concrete construction.
By adhering to ICC-ES AC454, manufacturers can demonstrate that their FRP bars comply with the required performance and safety standards. It also assists engineers, architects, and builders in selecting and designing appropriate FRP reinforcement for various concrete applications.
