Abstract:
This paper shows numerically the effect of the additional dynamic tension force on the dynamic
response of suspended cables. Since the nonlinear analysis is unable to show explicitly the effect of
additional dynamic tension force because of the coupling between the vertical and transverse modes and
the presence of nonlinear terms, the effect of additional dynamic tension force was studied using the linear
theory of cables. The effect of additional dynamic tension force shall first be shown on the natural
frequencies and vibration modes' shapes for various cables with different configuration parameters. The
dynamic response of two classes of suspended cables, one with considerable sag and another with shallow
sag are then presented to indentify the significance of additional dynamic tension force for both cases.
