Standard Specification for Uncoated Stress-Relieved Steel Wire for Prestressed Concrete
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers two types of uncoated stress-relieved round high-carbon steel wire commonly used in prestressed linear concrete construction, as follows:
1.1.1 Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage), and
1.1.2 Type WA wire is used for application in which the ends are anchored by wedges, and no cold-end deformation of the wire is involved (Wedge Anchorage).
1.2 Supplement I describes low relaxation wire and relaxation testing for that product.
1.3 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other, without combining values in any way.
