1.1 This specification covers uncoated high-strength steel bars intended for use in pretensioned and post-tensioned prestressed concrete construction or in prestressed ground anchors. Bars are of a minimum ultimate tensile strength level of 1035 MPa (150 000 psi). 1.2 Two types of bars are provided: Type I bar has a plain surface and Type II bar has surface deformations. 1.3 Supplementary requirements of an optional nature are provided. They shall apply only when specified by the purchaser. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification. |
