Abstract

The authors have applied a computer based model to perform spectral analysis of jacket platforms which treat structures in a consistent manner using the finite element method. The proper estimation of phasing effects ocean waves on structural responses is dependent, inter alia, on the accurate calculation of nodal forces; using the finite element approach the vector of nodal forces can be most accurately computed taking into account the varying distributed loads along structural members. The model calculates cross receptances of response for all degrees of freedom which enable the phase effects due to the spatial extent of the structure to be properly accounted for. As this model includes the effects of wave phase loadings on the platform it can thus give a more accurate estimation of response spectra which are generally require for design calculations.
