AB - This study investigated the mechanical properties of zinc-5% aluminium-mixed mischmetal alloy-coated steel strand cables (M-C cables) and internal steel wires under cyclic loading–unloading and a collaborative working mechanism by numerical analysis. Cyclic loading–unloading tests were performed on M-C steel wires with two sizes of cross section. The stress–strain curves, the nonlinear recovery characteristics of the M-C steel wires, and an exponential model of the relationship between the chord modulus and strain at the unloading point were obtained. Based on a mathematical model of the variable elastic modulus, a refined finite element analysis of normal M-C cables and locked M-C cables under loading–unloading was performed, and the correctness of the model was verified by comparisons with the test results. The stress development of each steel wire layer, the contact pressure between the steel wires, the influence of friction energy dissipation between the wires on the internal strain energy of the cable and the radial displacement of the cable under cyclic loading were investigated. The collaborative working mechanism for M-C cables and internal steel wires was evaluated.
