摘要：The analysis of the seismic vulnerability for a typical dwellingstructure, existing in a developed urban area, subjected to repetitive seismic actions, isperformed. This type of residential building is met all over Romania, making more than50% from the total number of buildings constructed in residential areas, built between1965 and 1985. The structure chosen for analysis is a P+4 building, made of precastconcrete panels. This type of building was selected because many districts in Iaşi havebeen built using this type of project or similar ones, within the mentioned period.The deterministic approach for evaluation is based on modelling and numericalsimulations using ETABS vs. 9 software. The methodology uses two types of numericalmodels. In the deterministic approach, for the first model, the building is considered in itsinitial state and for the second model in its degraded state, after the structure wassubjected to more than two or three major earthquakes. The degradations of the elementswere introduced taking into account nine scenarios, considering consecutively thestructural elements and the walls with openings having different degrees of damage, from30%, 60% to 90%.The obtained results study are used to classify the building structures based ontheir seismic risk and the degree of degradation, in order to fully comprehend andinvestigate the seismic vulnerability of the existing urban infrastructure.
