Abstract
The aim of this work is to undertake a comparison of vulnerability of a reinforced concrete building located on the Moroccan coast under a tsunami and a seismic load. Tsunami and seismic loads are evaluated through FEMA P646 and the Morocco seismic building code RPS2011 respectively. Thus, a case study building is analyzed by determining its reaction and displacements due to solicitations of each hazard separately. In order to determine the capacity of the building to each hazard, two methodologies are applied: time-history analysis and pushover. Next, fragility curves are plotted according to four damage states as a function of the inundation depth for tsunamis and of spectral displacement for earthquakes. A comparison is finally held between statistical data of past tsunami events and the reported impact data. In addition, a comparison between the impacts of these two hazards allows determining the associated threat limits and drawing recommendations so that buildings can resist tsunamis and earthquakes effects.
