Abstract
Avoiding resonances is of significant importance in designing multi-degree-of-freedom dynamic systems such as compliant deep-water offshore structures. This paper presents experimental evidence of the direct transfer of energy from high-to low-frequency modes in the analyses of the nonlinear response of frames and beams. In these experiments, structural elements are excited by a shaker; however, while there is no evidence that this mechanism has occurred in existing tension leg platforms (TLP) or models, there is no reason to believe that such a transfer could not take place. The phenomenon is most likely generic; hence, TPSs are most likely vulnerable.
