The increased number of ruptures in reinforcing ropes after short-time functioning may be associated with their manufacturing and operating conditions. The objective is to establish the main causes of premature breakage of high-strength reinforcement bars, based on the elemental and structural-phase composition of steel, mechanical properties of the wires, as well as the nature of the damaged surfaces and fracture characteristics. 18 Ref., 6 Tabl., 8 Fig.
