Responses for the June 2013 Committee Meeting (through May 16, 2013)

Wednesday, June 5, 2013

  1. AC308 Proposed Revisions to the Acceptance Criteria for Post-installed Adhesive Anchors in Concrete Elements. Revisions are proposed update the criteria to the 2012 codes and completely revise the criteria to reflect the anchor provisions of ACI 318-11 and the new ACI Standard ACI 355.4. This subject was previously considered by the Evaluation Committee in February 2013. Click here.

  2. 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.

  3. AC446 Proposed New Acceptance Criteria for Cast-in Specialty Inserts in Concrete. A new criteria is proposed to establish requirements for the recognition of cast-in specialty inserts in concrete that are subject to tension and shear loads. This subject was previously considered by the Evaluation Committee in February 2013. Click here.
  1. AC452 — Proposed New Acceptance Criteria for Rigid Cellular Polystyrene (RCPS) Geofoam Used in Interior Floor Applications. A new criteria is proposed to establish requirements for the recognition of rigid cellular polystyrene (RCPS) geofoam used as lightweight fill in floor cavities in the interior of buildings.

  1. AC449 — Proposed New Acceptance Criteria for Tension-Controlled Open Web Steel Joists. A new criteria is proposed which sets forth a new design methodology for long span steel joists (LH-series) and deep long span steel joists (DLH-series) joists which differs from the code-referenced Steel Joist Institute (SJI) design specifications. This proposal was introduced under the October 2012 alternative agenda process agenda and was previously considered by the Evaluation Committee in February 2013. Click here. (Updated)

  1. AC358 — Proposed Revisions to the Acceptance Criteria for Helical Pile Systems and Devices.  Revisions proposed by the Helical Pile Ad-Hoc Committee group as noted in their letter dated February 21, 2013.  Click here. (Updated)

  2. AC14 — Proposed Revisions to the Acceptance Criteria for Prefabricated Wood I-Joists. Revisions are proposed to apply the durability, corrosivity, and quality control provisions of Sections A4.4.2.3 and A4.4.4 through A4.4.6 for I-joists with factory applied paints, coatings, or treatments to I-joist used in fire-resistance-rated assemblies; add a new sentence to Section A4.4.1.5 to define the term “test duration” which is used in the first sentence of the section; revise Section A4.4.2.1 to insure that the intent of the provision is met (that the floor sheathing does not provide vertical support to the joists during the fire test); revise Section A4.4.2.3 to more clearly state the quality control requirements for factory applied paints, coatings, or treatments; revise Section A4.4.3 to require consideration of web holes in the tested assembly; and revise the testing for corrosion effects in Sections A4.4.4(c) and A4.4.4(d) based on input from report holders regarding the availability of ASTM A653 steel with a G60 coating designation. Portions of this proposal were introduced under the February 2013 alternative agenda process agenda. Click here.
  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 (Updated).
