Abstract


The aim of this work is to compare seismic vulnerability to tsunami one of structures located in the coastal area of Rabat-Salé, Morocco. Thus, in this study, a semi-empirical method is applied to determine the seismic vulnerability of the structures and a Time-history analysis is used to assess the vulnerability to the tsunami. Data on buildings typology are taken from the 2014 general population and housing census supplemented by the urban database available at the Rabat-Salé Urban Agency. The adopted approach yields fragility curves used to evaluate structural damage of the different types of buildings located in the coastal area of Rabat-Salé, Morocco. This comparison shows that the structures located in this coastal zone will suffer weak seismic damages compared to tsunami destructions for the seismic intensity VI that characterizes the Rabat-Salé zone and the height of the corresponding tsunami.
