This paper discusses the coupled soil-structure interaction analysis, results, and conclusions from the design of the Port of Nador being developed by the Moroccan Agency NWM. Located on the north coast of Morocco, the construction of the new industrial mega-port comprises over 5km of breakwaters and 3km of quayside to form two container terminals, petro-chemical berths, and solid fuel terminals. The design of the port has provided an opportunity to study post-earthquake performance of port structures including the onset and effects of liquefaction using advanced constitutive models. A performance-based design approach was adopted for the composite concrete caisson, nearshore and deep-water rubble mound breakwaters.
