Description

Technical Field

[0002] Steel strand is a product made of multiple steel wires twisted together. There are many types, such as prestressed steel strand used for bridges. Prestressed steel strand is a twisted steel cable composed of 2, 3, 7 or 19 high-strength steel wires. Retarded prestressing is a new structural technology that is developing rapidly. During prestressing, the linear friction loss K of the retarded steel strand is 50% greater than that of the unbonded prestressed steel strand and 200% greater than that of the bonded prestressed steel strand. As a result, under the same load conditions, the reinforcement of the retarded steel strand is 5% more than that of the unbonded steel strand and 10% more than that of the bonded steel strand.
