Haiti, because of his seismicity associated with plate boundary and several faults that cross the island of Hispaniola (Haiti-Dominican Republic), has been affected in the past by major earthquakes, which have caused loss of life and damage or considerable structural collapses (ex. 1771, 1842), sometimes the destruction of the cities. The recent earthquake of January 12, 2010, was the most destructive earthquake that any country has experienced in modern times, when we measure the number of people killed with respect to the population of a country (Cavallo et al. 2010). It's obvious that the major causes of theses losses are the lack of awareness of the population about the earthquakes, the absence of seismic code and quality control of the building. In this paper, we propose some recommendations for the establishment of the seismic code of Haiti in order to decrease physical and social impacts of earthquakes in the future. First of all, we present a theoretical part of concepts and fundamental elements to establish a seismic code, such as: description of the methodology for seismic hazard's assessment, presentation of the results in terms of acceleration maps for the whole country (in rock sites) and Uniform Hazard Spectrum (UHS) in the cities, and the criteria for soil classification and amplification factors for including site's effects, equivalent forces, etc. Then, we include a practical part where calculations and comparisons of five seismic codes of different countries (Eurocode 8, Spain, Canada, United States and Dominican Republic) are included, in order to have criteria for making the proposals for Haiti. Using the results of Benito et al (presented in this session S10) we compare the UHS in different cities of Haiti with the response spectrum derived from the application of the spectral shapes given by the aforementioned codes. Furthermore, the classification of soils and buildings have been also analyzed and contrasted with local data in order to propose the more suitable classification for Haiti. Finally, we have proposed a methodology for the forces estimation providing the values of the relevant coefficients.
