Theoretical investigation of rope strand subjected to axial tensile load

Abstract

Wire ropes or rope strands are one of the most important load carrying components of transportation systems such as bridge, elevator, crane and mine hoisting. Wire ropes must have high tensile strength in order to carry high tensile load. Wire ropes are mainly subjected to axial tensile load in service. This axial tensile load is exerted upon wires of rope or strand. Due to this reason tensile load causes elongation, strain and stress on the center wire (core wire) and outer wires. In this study, theoretical calculations proposed by Feyrer are adopted in order to determine wire loads, stresses, elongations and strains for axially loaded rope strands. An illustrative example is given.
