STOCHASTIC ANALYSIS OF ICE-STRUCTURE INTERACTION

The random response of an offshore structure due to forces caused by ice floes is studied. The loading, given by an actual field record obtained at Cook Inlet, Alaska, is assumed to be stationary and ergodic. The structure is idealized as a damped single-degree-of-freedom elastic system and the response obtained by the spectral method. A probabilistic dynamic analysis is presented in this paper for the response of fixed offshore structures to ice floes forced past them.
