ICC-ES AC526 – Acceptance Criteria for Glued-in Rods in Wood Structural Elements

Scope

ICC-ES AC526 establishes the acceptance criteria for evaluating factory-installed glued-in rods used in wood structural elements. These rods are typically threaded steel rods that are inserted into pre-drilled holes in wood members and bonded using adhesives. This type of connection is commonly used in timber construction for applications such as beams, columns, and trusses.

The scope of AC526 covers several key aspects, including:

  • Rod and adhesive properties: evaluation of the mechanical properties of the steel rods and the adhesive used for bonding to ensure they meet specific strength and durability requirements.
  • Connection performance: assessment of the load-carrying capacity and stiffness of the glued-in rod connections under various loading conditions, such as tension, compression, and shear.
  • Design and installation: evaluation of the design methodology and installation procedures for the glued-in rods to ensure proper placement, alignment, and bonding.
  • Environmental durability: assessment of the connection’s resistance to environmental factors such as moisture, temperature variations, and UV exposure.

The evaluation process typically involves a combination of testing, calculations, and review of manufacturer’s documentation to verify compliance with the acceptance criteria.
