Full Name

ICC-ES AC549 – Acceptance Criteria for Glued-in Perforated or Expanded Metal Plate(s) Used as Shear Transfer Element in Wood Concrete Composite Systems

Scope

ICC-ES AC549 outlines the acceptance criteria for evaluating glued-in perforated or expanded metal plates (GIPP or GIEP) used as shear transfer elements in wood-concrete composite systems. These systems combine the benefits of both wood and concrete, offering structural efficiency and versatility in building construction. The scope of AC549 includes:
  • Material properties: it specifies the requirements for the materials used in GIPP or GIEP connectors, including the type and grade of metal plates, adhesives, and wood species.
  • Design: it outlines the design criteria for GIPP or GIEP connectors, considering factors such as plate dimensions, perforation or expansion patterns, adhesive bond strength, and compatibility with the wood and concrete components.
  • Testing: it details the specific tests required to evaluate the performance of GIPP or GIEP connectors, including shear tests, pull-out tests, and fatigue tests, under various loading conditions.
  • Evaluation and certification: it outlines the process for evaluating and certifying GIPP or GIEP connectors to ensure they comply with the acceptance criteria and can be safely used in wood-concrete composite systems.
By adhering to ICC-ES AC549, manufacturers can demonstrate that their GIPP or GIEP connectors meet the necessary performance and safety standards. It also provides valuable information to engineers, designers, and builders for selecting and incorporating suitable shear transfer elements in their wood-concrete composite structures.
