ICC-ES AC434

Full Name

ICC-ES AC434 – Acceptance Criteria for Masonry and Concrete Strengthening Using Fabric-reinforced Cementitious Matrix (FRCM) and Steel Reinforced Grout (SRG) Composite Systems

Scope

ICC-ES AC434 outlines the acceptance criteria for evaluating the structural performance and safety of masonry and concrete strengthening systems that utilize Fabric-Reinforced Cementitious Matrix (FRCM) and Steel Reinforced Grout (SRG) composite systems. These systems are designed to enhance the load-carrying capacity, ductility, and durability of existing masonry or concrete structures. The scope of AC434 includes:
  • Material properties: it specifies the requirements for the materials used in FRCM and SRG systems, including the fabric reinforcement, cementitious matrix, steel reinforcement, and grout.
  • 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 FRCM and SRG 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 FRCM and SRG composites.
By adhering to ICC-ES AC434, manufacturers can ensure that their strengthening systems meet the necessary performance and safety standards. It also assists engineers, architects, and contractors in selecting and implementing appropriate strengthening solutions for existing structures.
