An experimental study of wire strains in an undamaged and damaged steel strand subjected to tensile load

Wire stráins in a wire-rope strand subjected to static and quasistatic tensile load are experimentally examined both before and after the cutting of one of the external wires. These tests are carried out with electrical-resistance strain gages. Significant differences between the most accepted Italian regulations and the measured values, obtained with the strand with one external wire severed, were noted.
