Presently, helically wrapped wire cables are used as the important load-carrying elements in many structures such as suspension bridges, cable-stayed bridges, tall guyed towers, power transmission lines, and flexible electrical conductors. In design and analysis, cables are traditionally assumed to carry axial load only; thus, studies on the bending behavior of the cables have been limited. Although the small curvature assumption of the cable may be valid for most part, the possible development of a large curvature at the bearings and anchorage cannot be ignored nor avoided. In this study, an analytical model was developed for the helically wrapped wires in a cable subjected to tension and small bending, with full consideration of the helically wrapped wire geometry. Using the developed model, an approximate upper limit of the cable curvature -for which the conventional Bemoulli-Euler-Navier kinematic beam assumption can be adapted to evaluate the stress in the wires- was obtained.
