Analysis of Operating Characteristics of Strands in Tension Allowing End-Rotation
1971
Chi, Michael
A rational analysis of wire strand in tension is made through the use of exact geometrical relationship and theory of mechanics of materials. The calculated strains, deformations and end-rotations of a strand agree well with the experimental data. Effect of the end-rotation on the load distribution in the wires of a strand is shown in detail. It was also found that the gap between the core and helical wires had a surprisingly high effect on the load distribution in the wires and the amount of end-rotation. The present construction of strands is critically analyzed and possible improved design is indicated. Finally, a truly non-spinning strand design is presented on the basis of this new method of analysis.
