A cable with sag is modeled by an truss with an equivalent modulus of elasticity in simplified analyses; but the cable deformation can not be determined. This study adopts Three-Dimensional elastic catenary cable elements in the finite element formulation of an cable to simulate its initial mode shape, nonlinear static behavior and nonlinear dynamic behavior. This paper also analyses three kinds of cable resonance. In the future, cable-stayed bridges will be analysed by the proposed approach.
