Wave-induced vibrations of flood gates: modelling, experimentation and design

Flood gates form an essential part of many flood defence systems in coastal areas. During storm events, these gates are subjected to extreme loads from various sources. This dissertation addresses the dynamic behaviour of flood gates induced by wave impacts. A semi-analytical fluid-structure interaction model is developed to predict vertical...

A fluid–structure interaction model for assessing the safety of flood gate vibrations due to wave impacts

This paper establishes a computationally efficient model to predict flood gate vibrations due to wave impacts including fluid–structure interaction. In contrast to earlier models, composite fluid domains are included to represent the situation of a flood gate in a dewatering sluice with the presence of an overhang that causes the confined-wave...

A three dimensional semi-analytical model for the prediction of gate vibrations immersed in fluid

A model is developed to predict bending vibrations of flood gates with fluid on both sides. The liquid flow is three-dimensional and the gate is represented as a thin plate. The fluid response is considered within the linear potential flow theory including the effect of compressibility and the generation of free surface waves. This way, the...
