    Rationale

    There has been an industry-wide effort over the past five years to accomplish several goals. First and foremost to modernize reinforced concrete design and construction. Secondly to incorporate higher strength reinforcing steel into seismic design. Thirdly, to determine the properties of the steel that are necessary to support the first two objectives. Review of international seismic design reinforcing standards was conducted, including standards from Japan, New Zealand, Australia, and Europe. Review of standards and additional Research was coordinated by the Charles Pankow Foundation, was funded by Pankow, the American Concrete Institute, the Concrete Reinforcing Steel Institute, and directly by cash contribution and material donations representing over 95% of the reinforcing steel manufacturers, was conducted by over eight different major universities and by researchers widely recognized as authorities on seismic design, several private practitioners, and was peer reviewed by other researchers, practitioners, manufacturers, and other industry partners. Research spanned a five year period, and represents a combined total of $26M in actual dollars spent, donated materials, and donated time. The universities involved in the research were UC Berkeley, UC San Diego, UT San Antonio, UT Austin, NC State, Perdue University, University of Kansas, and Kansas State, among others. Anyone interested in reviewing the research may find it at www.pankow.org. The Pankow Foundation has made all research related to building code modernization public domain. In order to support the afore-mentioned, industry-wide effort, this ballot is being written to update A706 on behalf of all afore-mentioned stakeholders with the improved properties necessary to support improved public safety, building design and construction, and to prevent explosion of inventory unnecessarily. It was discussed at length among the above participants, and the clear desire of industry was to update A706 to include all the requirements as balloted herein to maintain all seismic design reinforcing steel bar requirements in the A706 specification.
