ABSTRACT
The study of the seismic vulnerability of existing buildings in urban areas with moderate/high seismic risk is of extreme importance, as well as the evaluation of its safety, according to recently proposed international codes and recommendations. The large number of buildings, particularly modern architecture style buildings, constructed in Lisbon, Portugal in the fifties reveals deficient seismic behavior. In this chapter we present the main results of an existing building, representative of the modern architecture style, for which the seismic vulnerability was studied.
