ABSTRACT
Natural disasters can strike anytime and anywhere. It is, therefore, the duty of the civil engineer to make sure that buildings remain safe during the occurrence of such events. The paper presents a risk evaluation methodology for the Iasi Municipality, a city located in the North-Eastern Romania, characterized by an existing built-up area. The methodology is based on the non-linear finite element analysis of a specific class of residential buildings widely used in Romanian cities. The structural model is subjected to a real Romanian earthquake scenario in order to assess its behavior and degree of degradation developed during the life span of the structure. The visualization of the seismic risk of the considered structure in a selected urban sample is achieved by using NetSET GIS-software. This enables the mapping of the vulnerable areas affected by past earthquakes together with forecasting the seismic risk, both being key features for decision makers.
