Full Name
ICC-ES AC548 – Acceptance Criteria for Glued-in Perforated Metal Plate(s) in Wood Structural Elements
Scope
ICC-ES AC548 outlines the acceptance criteria for evaluating glued-in perforated metal plates used as connectors in wood structural elements. These plates are embedded within wood members and bonded using adhesives, providing reinforcement and enhancing the load-carrying capacity of the connection.
The scope of AC548 includes:
- Material properties: assessment of the mechanical properties of the perforated metal plates and the adhesive used for bonding, ensuring they meet specific strength and durability requirements.
- Connection performance: evaluation of the load-carrying capacity and stiffness of the glued-in plate connections under various loading conditions, such as tension, compression, and shear. This includes determining the characteristic values for the connections, which are used in design calculations.
- Design and installation: assessment of the design methodology and installation procedures for the glued-in plates to ensure proper placement, alignment, and bonding.
- Environmental durability: evaluation of the connection’s resistance to environmental factors such as moisture, temperature variations, and creep.
The evaluation process typically involves a combination of testing, calculations, and review of manufacturer’s documentation to verify compliance with the acceptance criteria.
