Abstract
The behaviour of the NO96 membrane containment system when
subjected to breaking waves is presented in this paper. The data
obtained from the full scale impact tests in the Sloshel project are
used. Uni-directional breaking waves were generated and interacted
with a real membrane containment system.
Three types of hydro-structural interaction can be distinguished
based on the relative position between load durations and natural
periods. The aim of this paper is to identify which type of interaction
occurred between the breaking wave and the NO96. It is
demonstrated that it is not straightforward to define the interaction
type by a comparison of observed load durations and predefined
mode shapes. As an alternative, it was investigated whether the
type of interaction can be deduced from its effect on the load and
on the response with respect to a quasi-static interaction.
