Pile-Supported Quay Submitted to Successive Earthquake and Tsunami Actions

Coastal regions are often associated with large and strategic structures, like ports and industrial or tourist exploitation. On the other hand, most harbours worldwide are in seismic and tsunami-prone regions, being the risk simultaneously increased by two inherent factors: the important societal role played by the ports and the exposure to the natural hazard. An efficient structural design decreases the vulnerability and, consequently, the risk; however, it implies a careful characterization of the acting loads. Aiming to investigate the successive earthquake and tsunami loading in a pile-supported quay of a deep-water port, is considered the seismic uncertainty associated to the region to estimate the ET actions. Two coupled models are required: 1) macro-scaled model, using FVM, to assess the hazard of the region, and 2) a meso/micro-scaled model, using SPH, to convert the physical parameters of the macro simulation into structural forces.
