ICC-ES AC Interim Criteria for Inspection and Verification of Concrete and Reinforced and Unreinforced Masonry Strengthening Using Fiber-reinforced. Accordance with. ICC-ES AC ADVANTAGES. DESCRIPTION/SUGGESTED SPECIFICATIONS*. The % epoxy resin and hardener are completely mixed. As such, Hilti maintains ICC-ES evaluation reports for adhesive anchors in concrete according to AC and in masonry according to AC I hope I have.

Organisation for Economic Co-operation and Development. Certification was deemed an important component icc-ex adhesive anchor usage, on par with certified welders for welding key structural steel connections.

Deep embedments are often difficult to achieve because the friction of cutting a thread can exceed the torsional capacity of the screw shank and fail the steel in torsion.

Strategic Highway Research Program. So, what is the state of the anchoring industry and where do the codes go from here?

AC – ICC Evaluation Service, LLC (ICC-ES)

Ready Mixed Concrete Association of Icf-es. Formal concrete anchorage design provisions first appeared in ACI as Appendix D, with applications limited to cast-in-place anchors and post-installed mechanical expansion anchors. Traffic Engineering Council Committee. Ministere des transports du Quebec MTQ. Transportation Association of Canada. Research testing of screw anchors has shown that failure can occur in tension via three modes: Aug, By Neal S.


The creation of the threads in the concrete gives the screw anchor some advantage in cracked concrete where a small-narrow crack intersecting the threads has only a minor reduction on tension capacity. Muncipal Engineers Association of Ontario. Society of Automotive Engineers. British Board of Agrement. Pullout failures look very much like bond failures for adhesively bonded anchors.

Undercutting of screw threads in concrete from Olsen, et. Hamilton Hydro-Electric System Specifications.

For post-installed mechanical anchors, anchors must be qualified to the criterion in the ACI This ic-ces the use of screw anchors a3c08 single-use item; removing and reusing the screw anchor in the drilled hole is not advised because the cutting threads on the screw are worn and getting the screw threads into the original cut threads in the concrete is difficult.

In Figure 1, the undercutting of the threads in the concrete is illustrated.

The new structural building code ACI will be re-organized based on member type. Deutsches Institut fur Normung e. Underwriters’ Laboratories of Canada. First Name Last Name.


Society for Protective Coatings. Ontario Statutes, Regulations, etc.

AC308 – Post-installed Adhesive Anchors in Concrete Elements

As of 15 Januarythe following actions were taken: Canadian Acts and Regulations. American Society of Civil Engineers. Adhesive anchors were incorporated into ACI under the premise that the existing design models would be minimally affected. To provide the mechanical interlock to the concrete, the screw anchor cuts a thread into the concrete during the installation process. Based partially on the Boston Big Dig tunnel accident, the adhesive anchor installer must be certified to install anchors in certain orientations and under certain load ac3308.

National Institute of Standards and Technology. They are intended to carry direct tension, direct shear, or combinations of tension and shear loadings.

International Concrete Repair Institute. But unlike other chapters in the re-organized Code, Chapter 17 essentially remained an untouched clone of Appendix D. National Asphalt Pavement Association.
