In this paper a spline finite element model is derived to analyze dynamic stability of cables and cable structures. The total form of strain is adopted in computation to ensure the convergence of iterations under large displacement increments. The nonlinear stability of elastic inclined cables under cyclically loading is investigated. The effects of the concentrated and distributed loads on cables are analyzed. The reactions of excited cables are studied. Numerical examples are conducted to study the dynamic behaviors of simple structure supported by the cables in parametric resonance zones. It shows that the parametric instability of cables must be carefully dealt with in engineering.
