Abstract: The nonlinear dynamic behavior of flexible offshore structures in waves is studied using both analytical and numerical approaches. In particular, the phenomenon of subharmonic oscillation of order 1/2 is investigated. From ...

Abstract: In order to carry out nonlinear dynamic analyses of fixed offshore structures in the frequency domain, polynomial approximations of the distributed drag term,

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 ...

Abstract: Besides the commonly considered drag force, inundation due to variable water surface is another important nonlinear effect of wave loading. Quadratic and quartic approximations of the inundation ...

Abstract: The performance of an eccentrically braced frame designed to yield in shear is investigated by the pseudo‐dynamic test. This relatively new experimental technique is suitably modified to account for the effect of inherent ...

Abstract: The possibility of making short-term prediction of rainfall is studied by investigating the existence of chaotic behavior in the rainfall data series. The minimum number of variables essential and the number of variables ...
