Full Name

ICC-ES AC416 – Acceptance Criteria for Enhanced Light-frame Shear Walls Using Glass Fiber-reinforced Polymer (GFRP) Composite Systems

Scope

ICC-ES AC416 outlines the acceptance criteria for enhancing light-frame shear walls using Glass Fiber-Reinforced Polymer (GFRP) composite systems. These systems are designed to improve the structural performance of wood-framed walls, particularly their resistance to lateral forces like wind and earthquakes.

The scope of AC416 includes:

  • Materials: it specifies the requirements for the GFRP composite materials, including the type of fibers, resins, and adhesives used, ensuring their compatibility and durability.
  • Design and construction: it details the design and construction requirements for the enhanced shear walls, including the configuration of the GFRP reinforcement, attachment methods to the wood framing, and any additional structural elements.
  • Performance: it outlines the testing methods and acceptance criteria for evaluating the performance of the enhanced shear walls, including their shear strength, stiffness, and energy dissipation capacity under simulated seismic and wind loads.
  • Installation: it provides guidelines for the proper installation of the GFRP composite systems, ensuring they are correctly applied and integrated with the light-frame construction.
  • Quality control: it establishes a quality control program for manufacturers to ensure that the GFRP composite systems consistently meet the requirements of the acceptance criteria, including inspections and testing procedures.

The AC416 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their GFRP composite systems comply with the applicable building codes and standards.
