ICC-ES AC436
Full Name
ICC-ES AC436 – Acceptance Criteria for Establishing Seismic Equivalency to Code-prescribed Light-frame Shear Walls Sheathed with Wood Structural Panels Rated for Shear Resistance or Steel Sheets
Scope
ICC-ES AC436 outlines the acceptance criteria for evaluating alternative shear wall systems and establishing their seismic equivalence to code-prescribed light-frame shear walls sheathed with wood structural panels rated for shear resistance or steel sheets. ICC-ES AC436 is intended for manufacturers seeking approval for their alternative systems under the ICC-ES evaluation report program.
The scope of AC436 covers:
- Alternative shear wall systems: defines the types of alternative shear wall systems that can be evaluated, including those with different sheathing materials, framing configurations, or connection details.
- Seismic equivalency: establishes the criteria for determining if an alternative shear wall system provides equivalent seismic performance to the code-prescribed shear walls. This includes requirements for strength, stiffness, and energy dissipation.
- Test methods: outlines the specific tests and procedures to be followed to evaluate the seismic performance of the alternative shear wall systems, including static and cyclic testing.
- Analysis methods: specifies the analytical methods that can be used to supplement the test data and provide additional evidence of seismic equivalence.
- Quality control: details the quality control measures that manufacturers must have in place to ensure consistent product quality and compliance with the acceptance criteria.
