The specific cause of the damage is unknown. In this research the role of the dynamic behaviour of a jetty investigated. This research has the goal to elaborate circumstances under which the dynamic behaviour of the open piled jetty on Sint Maarten significantly enlarges the amplitude of vibration, when being subjected to wave loading. This is investigated by simulating the water surface and corresponding wave loading in the time domain and computing the dynamic response for the first jetty of Sint Maarten for different wave climates. Wave loading on the jetty deck and the piles are included in three directions. For the wave loading on the deck (slamming/wave-in-deck loading) a new formulation is derived in this research, in order to get a formulation which is dependent of time and location which is essential for a dynamic analysis. This new formulation is based on results of physical model tests performed for the situation of Sint Maarten. The dynamic analysis is performed by modal analysis in the time domain, without including non-linear interaction between the travelling waves and jetty structure. The response of the structure to the wave loading is analysed using the variance spectrum of the displacement, dynamic amplification factor and displacement signal. From the results it can be concluded that the dynamic behaviour of the jetty of Sint Maarten significantly enlarges the amplitude of vibration in horizontal direction for the investigated wave spectra. In vertical direction the maximum displacement decreases due to the dynamic behaviour. For further research verification of the dynamic behaviour of an open piled jetty and improvement of the wave-in-deck pressure are recommended.
