DYNAMIC RESPONSE OF DAMAGED CABLE-STAYED BEAM

An elastic continuous model is presented for the in-plane dynamic motion of the cable-stayed beam with cable damage. The linear eigenmodes are obtained via the method of reverberation-ray matrix after a standard condensation procedure. A singledegree- of-freedom non-linear model is obtained by the single-mode discretization. The homotopy analysis method is then successfully applied to get the frequency-amplitude relationship, which enables us to characterize the influence of cable damage on the nonlinear dynamic behaviour of the system.
