ACI - ITG 4.2R-06 Materials and Quality Considerations for High-Strength Concrete in Moderate to High Seismic Applications

The lower 6000 psi (41 MPa) threshold, however, was chosen for the ITG-4 document because it deals with a specialized application of high-strength concrete application in areas of moderate to high seismicity. An accompanying standard, ITG-4.1 (available Spring 2007), is written in mandatory language in a format that can be adopted by local jurisdictions, and will allow building officials to approve the use of high-strength concrete on projects that are being constructed under the provisions of ACI 301 and 318. ITG-4.2R is the supporting document for that standard. ITG 4 has also developed another non-mandatory language document: ITG-4.3R (available Spring 2007). It addresses structural design and detailing considerations. 30 pp.
