Items for the June 2014 Evaluation Committee Meeting

Tuesday, June 3, 2014

  1. AC232 — Proposed Revisions to the Acceptance Criteria for Anchor Channels in Concrete Elements. Revisions are proposed to replace the determination of flexural strength of the anchor channel with an approach using the mending moment in various sections of Annex A; delete the determination of pull-out strength from Annex A, Section 8.9.2; make a number of editorial changes to Annex A; and revise Annex A, Table 4.1, test series 7 so that these tests may be omitted under certain conditions.

  2. AC308 — Proposed Revisions to the Acceptance Criteria for Post-Installed Anchors in Concrete Elements. Revisions are proposed to Table 8.1 and Section 8.5 of Annex 1 which would allow recognition of post-installed adhesive anchors in an additional optional Temperature Category C. Click here.
  3. AC454— Proposed New Acceptance Criteria for Glass Fiber-Reinforced Polymer (GFRP) Bars for Internal Reinforcement of Concrete Members. A new criteria is proposed to establish requirements for GFRP bars that are solid and have a circular cross section, or solid but have a cross section other than circular, or hollow and have circular cross section, used as flexural reinforcement in tension to reinforce structural concrete members. Portions of this proposal were introduced under the August 2013 alternative criteria development process agendas. Click here.
  4. AC70 — Proposed Revisions to the Acceptance Criteria for Fasteners Power-driven into Concrete, Steel, and Masonry Elements. Revisions are proposed to expand the permitted uses of the fasteners driven into steel base materials when the fasteners have been qualified in accordance with Annex A; revise the safety factor in Annex A in situations where the COV from residual strength tests exceeds 15 percent; to add provisions to have the evaluation report to indicate that the allowable loads in the report apply to the connection of the fastener to the base material only; clarify where fasteners may be used without qualification of the fastener finish; reconcile a discrepancy within the criteria regarding acceptable overstrength of the concrete base material used in qualification testing; and provide editorial clarifications.

  5. AC116 — Proposed Revisions to the Acceptance Criteria for Nails. Revisions are proposed to clarify that nails formed from hot-dipped galvanized wire are permitted and do not need to be qualified in accordance with AC257; clarify that the coating thickness on the finished nails need to be verified; further define the nail characteristics that are required for prescriptive use of nails in shear walls, braced walls and diaphragms; and allow shear wall and diaphragm values to be developed from smooth shank nails with diameters that are smaller than those prescribed on SDPWS for use in shear walls and diaphragms. Portions of this proposal were introduced under the February 2014 alternative criteria development process agenda. Click here.
  6. AC233 — Proposed Revisions to the Acceptance Criteria for Alternate Threaded Fasteners. Revisions are proposed to add an annex to the criteria to allow optional recognition the fasteners installed at an angle to the grain of other than 90 degrees; add provisions to address the use of the fasteners in engineered wood; modify provisions of the criteria to give applicants the option of qualifying screws for use in diaphragms, shear walls and braced walls in accordance with AC120; and modify the criteria to reflect our current inspection policies and to change the required inspection frequency. Portions of this proposal were introduced under the October 2013 and February 2014 alternative criteria development process agendas. Click here.
  7. AC120 — Proposed Revisions to the Acceptance Criteria for Wood-frame Horizontal Diaphragms, Vertical Shear Walls and Braced Walls. Revisions are proposed to allow alternative fasteners to have nail slip characteristics exceeding the slip exhibited by benchmark fasteners in certain engineered applications. Click here.
  8. AC316 — Proposed Revisions to the Acceptance Criteria for Shrinkage Compensating Devices. Revisions are proposed to include movement associated with the method used to attach the device to the structure when determining the average travel and seating increment of the device in cases where attachment of the device to the structure is necessary for the device to actuate.
