Static Response of a Wire Rope

Abstract

The equations developed in the previous sections will now be used to generate the solution for ropes with complex cross sections. Consideration will be given, at first, to a cross section consisting of one simple, straight, seven-wire strand surrounded by six seven-wire strands, which are preformed. Figure 4.1 shows such a cross section in which the outside strands are deformed into the helical shape they assume in the unloaded rope and are this shape under no external loads (preformed strands). Such a cross section is often used as a rope core in a more complex rope and as such is sometimes called an independent wire rope core (IWRC). The center strand will be called strand 1, an outside strand will be denoted strand 2.
