ICC-ES AC13 – Acceptance Criteria for Joist Hangers and Similar Devices


ICC-ES AC13 establishes requirements for ICC-ES recognition of various types of connectors used in wood construction under the International Building Code (IBC) and the International Residential Code (IRC).

The scope of ICC-ES AC13 includes:

  • Joist hangers: devices used to connect joists to supporting beams or ledgers.
  • Framing anchors: connectors for various wood framing connections, such as hold-downs and tie-downs.
  • Hurricane ties: specialized connectors designed to resist high winds and seismic forces.
  • Similar devices: other types of connectors used in wood construction that fall under the general category of joist hangers and framing anchors.

The criteria in ICC-ES AC13 cover various aspects of these connectors, such as:

  • Materials: requirements for the materials used in the connectors.
  • Design: design criteria for the connectors, including strength and stiffness requirements.
  • Testing: test methods for evaluating the performance of the connectors.
  • Installation: requirements for the proper installation of the connectors.

By meeting the requirements of ICC-ES AC13, manufacturers can obtain an evaluation report from ICC-ES, which demonstrates that their products comply with the building codes and are suitable for use in construction projects.
