ICC-ES AC213 – Acceptance Criteria for Glass Shear Walls and Diaphragms for Patio Covers


ICC-ES AC213 establishes the acceptance criteria for glass shear walls and diaphragms specifically designed for use in patio covers. It outlines the requirements for these components to be recognized in an ICC-ES evaluation report under the International Building Code (IBC).

Key aspects covered by AC213 include:

  • Materials: specifies acceptable types of glass and framing materials for shear walls and diaphragms in patio covers.
  • Structural design: outlines design requirements to ensure these components can withstand wind and seismic loads, considering factors like glass thickness, framing configurations, and connection details.
  • Testing: details the testing procedures and performance criteria these components must meet to demonstrate their structural adequacy and safety.

By defining these criteria, AC213 ensures that glass shear walls and diaphragms used in patio covers are safe, durable, and compliant with the building code, providing building officials, designers, and consumers with confidence in their performance.
