Daftar Isi:
- A method, called spectral response surface method, is proposed for the study of the ringing phenomenon of offshorestructures. Newman’s results for diffraction force on a column were reformulated in terms of the frequency componentsof the ocean surface and their Hilbert transforms. Using a first-order reliability method together with a dynamic modelfor the structural response, it is straightforward to calculate the ocean surface history most likely to generate an extremeringing response and the ringing response history.Keywords: ringing, spectral response surface, first-order reliability method
