Full Name
ICC-ES AC283 – Acceptance Criteria for Metal Hinge Plate Connectors for Wood Trusses
Scope
ICC-ES AC283 establishes the acceptance criteria for metal hinge plate connectors used in wood trusses. These connectors are installed in pairs in a 180-degree position on opposing faces of a wood truss joint to create a hinged connection.
The scope of AC283 includes:
- Materials: specifies the types of materials allowed for the metal hinge plates, such as steel or aluminum, and their required properties like yield strength and thickness.
- Design and fabrication: outlines the design and fabrication requirements for the hinge plates, including dimensions, shape, hole patterns, and edge distances.
- Performance: sets out the performance criteria that the hinge plates must meet, such as the allowable design loads for tension, shear, and moment in different configurations.
- Testing and evaluation: details the testing procedures that must be conducted to verify that the hinge plates comply with the acceptance criteria. This includes both laboratory testing for strength and stiffness, as well as in-situ testing of assembled trusses.
By establishing these acceptance criteria, ICC-ES AC283 ensures that metal hinge plate connectors used in wood trusses are safe, reliable, and meet the necessary building code requirements. It provides a standardized framework for manufacturers, designers, and building officials to assess the suitability of these connectors for various truss applications.
