Abstract


Wave induced uplift pressures and forces have been investigated by smalland large-scale model tests. Detailed analyses of waves at the structure, forces and structure motions showed that conventional design formulae neglect details of pressure development which contribute to the total uplift force. Direct comparison between quasi-static, dynamic forces and the commonly used formulae show that dynamic effects exhibit a significantly different behaviour in comparison to those observed during quasi-static wave attack. The most relevant of the effects which may be useful for setting up a numerical model for the prediction of uplift pressures are described.
