Full Name
ICC-ES AC521 – Acceptance Criteria for Fiber-reinforced Polymer (FRP) Bars and Meshes for Internal Reinforcement of Non-structural Concrete MembersScope
ICC-ES AC521 outlines the requirements for evaluating Fiber-reinforced Polymer (FRP) bars and meshes used as internal reinforcement in non-structural concrete members. It aims to establish guidelines and requirements for these alternative reinforcements where traditional building codes lack specific provisions. The scope of AC521 encompasses:- Material properties: it specifies the requirements for the physical and mechanical properties of FRP bars and meshes, 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 and meshes under different loading conditions, such as tension, compression, and bending.
- Design: it outlines the design procedures for using FRP bars and meshes as internal reinforcement in non-structural concrete members, considering factors like bond strength, anchorage, and serviceability limits.
- Evaluation: it provides a framework for evaluating FRP bar and mesh products to ensure they meet the acceptance criteria and can be safely used as alternatives to steel reinforcement in non-structural concrete applications.
