Study Concerning the Level of Seismic Risk in Iasi Municipality

Throughout its history, Iasi municipality has been subjected to many important seismic actions caused by earthquakes produced in Vrancea area, Romania. The impact of these extreme events upon the town increased in time as it developed, more buildings were constructed and the population density rose. The classes of buildings identified in Iasi municipality have been designed on different seismic standards, some of them being erected without taking into account the effect of seismic actions. The differences between the seismic norms’ regulations and the important earthquake’s history some of the buildings have, are outlining the need of seismic risk assessment in Iasi municipality. This paper aims to present some of the results of the seismic risk study in Iasi municipality, which was based on the completed seismic risk surveys and on the regulations of seismic standards. In this study, only the dwelling structures built before 1990 were considered, and the results were distributed on neighborhoods, for obtaining a general perspective on the seismic risk state of each area, by considering the buildings’ seismic vulnerability.
