Previous research on risk in a central area of Barcelona, called the Eixample, have showed middle and high building vulnerability indices, in agreement with the actual state and the design details of the analyzed buildings. The seismic scenarios simulated for this area showed an unadequate seismic performance for reinforced concrete buildings. These structures presented a high risk, especially the flat-slab buildings. This fact motivated to proceed with the seismic risk studies in other areas of the city, in order to propose seismic risk mitigation measures.
The aim of this work is to apply the italian vulnerability index method in the evaluation of the structural seismic quality of buildings for these new areas of Barcelona. This evaluation metodology is adequate in vulnerability studies for large urbans zones. Furthermore, the vulnerability functions obtained for non-reinforced masonry and reinforced concrete buildings existing in Barcelona will be applied to asses the seismic risk for different levels of macroseismic intensity.
Finally, the results, which are basically vulnerability indices, will be implemented in a Geographical Information Systems to develop probable damage scenarios.
