The paper presents the research results regarding the effect of compaction of highstrength prestressing strands of the 1х7 (1+6) design on changes in the stress-strain state of steel. After stranding wires in high-strength prestressing strands with strength of 1860 MPa, 12.5 mm in diameter, the strand should be compacted at a suggested degree of 6 %. This reasonable schedule of compaction contributes to a lower level of stranding stresses, integral strand geometry and residual stresses within the ranges compatible with residual stresses of stabilized prestressing strands. The paper includes the studies on mechanical properties of test specimens of compacted prestressing strands. A computer model of stranding and subsequent compaction of strands is used to factor in residual stresses formed at previous operations of strand production.
