| Abstract: |
| A finite-volume formulation for the analysis of largedeflection dynamic characteristics and dynamic responses of suspended cables is established based on the principle of Lagrange.The explicit expressions of the nodal force vector,mass and tangent stiffness matrices are presented.A particularly important feature of the present formulation is the use of the engineering strains instead of the Green strains for defining the cable deformations.As a result the formulation is simple and has a clear physical meaning.Numerical examples for the analysis of dynamic characteristics and stochastic wind-excited responses are given.The obtained results indicate that the present method is accurate and efficient and is applicable to large-deflection dynamic analysis of suspended cables in any sag and loading conditions. |
