CSA G279-M1982 (R1998) PDF Download

The CSA G279-M1982 (R1998) standard (Metric version), provides guidelines for the use of various types of steel in prestressed concrete construction. The standard covers uncoated stress-relieved and low-relaxation smooth round wire, uncoated seven-wire stress-relieved and low-relaxation strand, and high-strength stress-relieved alloy steel bars used in prestressed concrete construction.

The requirements outlined in the standard are applicable to these types of wire, strand, and bars unless otherwise specified. The standard also provides specific guidelines for the use of round high-carbon steel wire in prestressed concrete construction, specifically in button-head-type (cold-end-deformation) and wedge-type anchorage. The use of quenched and tempered wire is not permitted.

Regarding strand, the standard covers seven-wire, uncoated, stress-relieved and low-relaxation steel strand to be used in pre-tensioned and post-tensioned pre-stressed concrete construction. Similarly to wire, the use of quenched and tempered wire is not permitted.

In addition, the standard covers plain or deformed high-tensile strength alloy bars with a nominal diameter greater than 9 mm. The use of quenched and tempered bars is not permitted. The standard also provides supplementary requirements that are optional and only applicable when specified by the purchaser.
