Standard Specification for Steel Strand, Uncoated Seven-Wire for Prestressed Concrete
|Publication Date:||10 September 1999|
|ICS Code (Steels for reinforcement of concrete):||77.140.15|
1.1 This specification covers two types and two grades of seven-wire, uncoated steel strand for use in pretensioned and post-tensioned prestressed concrete construction. The two types of strand are low-relaxation and stress-relieved (normal-relaxation).
1.2 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
