Spectral Analysis of Offshore Structures Under Wave and Earthquake Loadings

Chapter
Part of the Springer Series in Reliability Engineering book series (RELIABILITY)

Abstract

This chapter presents spectral analysis of offshore structures under wave and earthquake actions. It contains six sections. The first section explains problem description and gives some general information. In the second section, formulation of dynamic analysis of offshore structures in the frequency domain, transfer functions of wave, and earthquake forces are presented. The third section presents response transfer functions of wave and earthquake forces individually. Then, having presented hydrodynamic and inertia forces produced by earthquakes, response transfer functions of their combined effect are formulated. The fourth section explains calculation of response spectra of offshore structures under stochastic wave and earthquake forces. Then, the stochastic ground motion under earthquakes and its spectral representation are presented. It follows the calculation of transfer functions and response spectra of offshore structures under nonuniform earthquake ground motions. In section five, calculation of response statistical quantities is presented and. In section six, numerical demonstration of an example offshore structure is given.
