ICC-ES AC154 – Acceptance Criteria for Cyclic Racking Shear Tests for Metal-sheathed Shear Walls with Steel Framing

Scope

ICC-ES AC154 outlines the acceptance criteria for evaluating the racking shear performance of metal-sheathed shear walls with steel framing. These criteria ensure that the shear walls meet the structural requirements of building codes like the International Building Code (IBC) and the International Residential Code (IRC).

Key aspects covered within the scope of AC154 include:

  • Cyclic racking shear test: outlines the procedure and requirements for conducting cyclic tests to assess the shear wall’s resistance to lateral loads.
  • Load-displacement relationship: evaluation of the shear wall’s behavior under increasing lateral loads, including its stiffness, strength, and ductility.
  • Energy dissipation: assessment of the shear wall’s ability to dissipate energy through inelastic deformation, which is crucial for earthquake resistance.
  • Failure modes: identification and evaluation of potential failure modes, such as sheathing buckling, fastener failure, or frame yielding.
