Code of Federal Regulations. Pullout failures look very much like bond failures for adhesively bonded anchors.

They ax308 intended to carry direct tension, direct shear, or combinations of tension and shear loadings. American Iron and Steel Institute. 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.

International Slurry Surfacing Association. 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. As of 15 Januarythe following actions were taken: Neal may be reached at nsanderson sgh. Traffic Engineering Council Committee. Insulating Cable Engineers Association. There are a wide variety of post-installed concrete anchors, and the newest post-installed anchor is the screw anchor.

The Present State of the Industry 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.

National Asphalt Pavement Association. This makes the use of screw anchors a single-use item; removing and reusing the screw anchor in the drilled hole is ivc-es advised because the cutting threads on ac3008 screw are worn and getting the screw threads into the original cut threads in the concrete is difficult.

This was a conscientious decision by the Code Committee at the beginning of the reorganization work, because: Society of Automotive Engineers. American Wood Protection Association.
