ICC-ES AC490
Full Name
ICC-ES AC490 – Acceptance Criteria for Concrete and Reinforced and Unreinforced Masonry Strengthening Using Externally Bonded Steel-reinforced Polymer (SRP) Composite SystemsScope
ICC-ES AC490 outlines the acceptance criteria for evaluating the strengthening of existing concrete, reinforced masonry, and unreinforced masonry structures using externally bonded steel-reinforced polymer (SRP) composite systems. These systems are applied to the exterior of the structure to enhance its load-carrying capacity and improve its structural performance. The scope of AC490 includes:- Materials: it specifies the requirements for the materials used in SRP systems, such as the steel reinforcement, polymer matrix, and bonding agents.
- Design: it outlines the design criteria for strengthening systems, considering factors like the type of structure, load conditions, and desired performance enhancements.
- Testing: it details the specific tests required to evaluate the performance of SRP systems under various loading conditions, including tensile, shear, and flexural tests.
- Evaluation: it provides a framework for evaluating the structural adequacy and safety of masonry and concrete strengthening systems using SRP composites.
