Characteristics of buildings and seismic vulnerability assessment for the specific area of the city of Osijek

Abstract

Seismic risk is a measure of the damage that is expected in a specific area and time interval. It is based on the level of seismicity of locations (hazard), the resistance of buildings (vulnerability), and the type, quality and quantity of exposed assets (exposure). It can be measured by the expected economic loss, loss of life or damage to property size. Reducing the seismic risk comprises three phases: assessment, planning and implementation. The risk assessment requires a multidisciplinary approach that takes into account the expected physical damage (damage to buildings and economic losses), as well as social, organizational and institutional factors. At the city level, a risk assessment should start assessing the physical damage as a result of basic tools and the link between risk and vulnerability values of buildings. In this paper the creation of a database of existing buildings, classification of buildings and a procedure for determining the building typology that prevail in the city of Osijek is described. Based on the formed database, it is possible to implement certain seismic vulnerability methods.
