|Title:||Response spectrum estimation for fixed offshore structures with inundation effect included: A Price's theorem approach||Authors:||Zheng, X.Y.
|Issue Date:||Nov-2004||Citation:||Zheng, X.Y., Liaw, C.Y. (2004-11). Response spectrum estimation for fixed offshore structures with inundation effect included: A Price's theorem approach. Journal of Offshore Mechanics and Arctic Engineering 126 (4) : 337-345. ScholarBank@NUS Repository. https://doi.org/10.1115/1.1834623||Abstract:||Instead of a Volterra-series based method, a method based on Price's theorem and Fourier Transforms is proposed for evaluating the nonlinear response power spectra of fixed offshore structures modeled as finite-memory systems. The numerical computation effort required for spectral estimations using the proposed method is significantly less than that of the Volterra-series method that requires multi-dimensional integrations. Nonlinear frequency-domain analyses of two jack-up platform structures are carried out to study the effects of inundation, cubic and quartic drag terms and polynomialization methods.
