This paper presents a GIS-based methodology for monitoring the seismic performance, while taking into account the deteriorations revealed during GIS-based scenarios aiming at the identification of the seismic serviceability of the structure. By applying the geographical information system (GIS) containing geospatial data, one can develop useful scenarios to improve the knowledge on structural vulnerability of the urban built infrastructure. Based on our research, we present a way of applying decision trees to risk analysis of possible earthquakes in potential regions with high seismic risk. Scenarios of modeling, simulation and nonlinear seismic analysis are described and applied to a class of damaged models for some of the RC structure typical of the existing urban infrastructure of Iasi, Romania. The management of GIS-based seismic vulnerability of existing concrete structure is presented as a tool for awareness and mitigation of seismic effects of possible future events in the urban area.
