ICC-ES AC47

Full Name

ICC-ES AC47 – Acceptance Criteria for Structural Wood-based Products

Scope

ICC-ES AC47 establishes guidelines for evaluating structural wood-based products used as alternatives to sawn lumber for wall, floor, and roof structural members. The scope includes:
  • Materials: it covers a wide range of structural wood-based products, such as cross-laminated timber (CLT), glued laminated timber (glulam), laminated veneer lumber (LVL), and other engineered wood products.
  • Design: it outlines the design requirements for structural wood-based products, including considerations for strength, stiffness, and stability under various load conditions.
  • Testing: it details the specific tests required to evaluate the structural performance of wood-based products, such as bending, shear, and connection tests.
  • Evaluation: it provides a framework for evaluating structural wood-based products to ensure they comply with the acceptance criteria, including a review of their design, material properties, and test results.
ICC-ES AC47 is essential for manufacturers to demonstrate that their structural wood-based products meet the necessary performance and safety standards. It also assists building officials, designers, and engineers in selecting and using appropriate wood-based products for their projects.
