  1. AC232 Proposed Revisions to the Acceptance Criteria for Anchor Channels in Concrete Elements. Revisions are proposed to the criteria to revise footnote 5 to Table 4.1 in Annex A; add test requirements for anchor channels loaded in shear perpendicular to the channel axis as well as the calculation of the concrete edge breakout resistance in shear; and add optional testing requirements for anchor channels loaded in the direction parallel to the channel axis as well as for recognition to resist seismic loads.

  1. AC440 — Proposed New Acceptance Criteria for Using an Equivalency Approach to Verify Seismic Design Parameters for Lateral-Force-Resisting Vertical Wood Truss Wall Assemblies. A new criteria is proposed to provide requirements confirming the use of metal-plated wooden trusses, referred to as wood truss wall assemblies (WRWA), as substitutes for in-plane shear-resisting vertical components (shear walls) of an otherwise code-complying lateral force-resisting system. This subject was previously considered by the Evaluation Committee in October 2012. Click here.
