This　study　investigated　the　mechanical　properties　of　zinc-5%　aluminum-mixed　mischmetal　alloy-coated　steel　strand　cables　(M-C　cables)　with　diameters　ranging　from　12　mm　to　22　mm.　A　total　of　24　tensile　tests　were　conducted　to　obtain　the　nominal　yield　strength,　ultimate　strength,　elastic　modulus,　fracture　strain,　and　stress-strain　curves　for　M-C　cables　with　varying　diameters.　The　stress-strain　curves　of　the　test　specimens　were　fitted　using　the　modified　Ramberg　and　Osgood　models　to　obtain　stress-strain　models　for　M-C　cables　with　different　diameters.　Based　on　the　actual　boundary　of　the　cable　used　in　engineering　practice,　a　new　finite　element　model　was　established　with　ABAQUS　finite　element　analysis　software.　Based　on　the　finite　element　model,　the　development　of　the　stress　in　each　layer　of　steel　wire,　change　in　the　contact　pressures　between　the　wires,　and　the　friction　energy　dissipation　between　the　wires　were　analyzed　with　continuous　elongation　of　the　cable.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
