Abstract

This paper deals with a fast spectral analysis of structures subjected to both wind and wave loadings. It hinges on the Multiple Timescale Spectral Analysis, which is a framework generalizing the Background/Resonant decomposition and offering therefore a very rapid compu- tation of the statistics of the structural responses. The theory developed in this paper aims at the determination of the second-order response of a floating bridge. Similar concepts are applicable to other floating structures, whose natural frequencies lies between the typical frequency bands of wind and wave loadings.
