ICC-ES AC262
Full Name
ICC-ES AC262 – Acceptance Criteria for Horizontal Diaphragms Consisting of Wood Structural Panel Sheathing Attached to Cold-formed Steel Framing
Scope
ICC-ES AC262 establishes the acceptance criteria for evaluating the structural performance of horizontal diaphragms constructed with wood structural panel sheathing attached to cold-formed steel framing. These diaphragms are crucial components in building structures, resisting lateral loads caused by wind or earthquakes.
The scope of AC262 includes:
- Materials: it specifies the requirements for wood structural panels and cold-formed steel framing, ensuring their compatibility and suitability for diaphragm construction.
- Fasteners: it outlines the types and spacing of fasteners allowed for attaching the sheathing to the framing, ensuring adequate strength and connection.
- Design and performance: it provides criteria for evaluating the design and performance of diaphragms under various loading conditions, including shear strength and deflection.
- Testing procedures: it specifies standardized test methods for assessing the shear capacity and stiffness of diaphragms.
By adhering to AC262, manufacturers and designers can ensure that their horizontal diaphragms meet the necessary standards for structural integrity and safety in building applications.
