The purpose of this method was to establish the seismic priority index (spi) resulting from the addition of the structural (si) and non structural (nsi) indices as shown in eq. (3). this screening score major factors have been; building location, soil type, duration or age of occupancy, falling hazard, and others.

Ppt Earthquake Risk Reduction 1 Concepts Terminology Powerpoint Figure 3. seismic hazard distribution (for non exceedance probability of 90 % in 50 years) vulnerability of the existing building stock another part of the procedure is dedicated to analysis of seismic vulnerability. the seismic vulnerability implies the expected degree of damage to a given element at risk resulting from a given level of seismic. Seismic risk evaluation of built up areas involves analysis of the level of earthquake hazard of the region, building vulnerability and exposure. within this approach that defines seismic risk, building vulnerability assessment assumes great importance, not only because of the obvious physical consequences in the eventual occurrence of a seismic event, but also because it is the one of the few. In 2003, as part of the enserves project (european network on seismic risk, vulnerability, and earthquake scenarios) – a research consortium funded by the european commission that gathered teams of scientists of different specialties from eleven international institutions –, (dolce et al., 2003) derived dpms for the italian town of potenza. Seismic fragility and vulnerability assessment is an essential step in the evaluation of probabilistic seismic risk. ideally, models developed and calibrated for the building portfolio of interest would be readily available. however, the lack of damage data and insufficient analytical studies lead to a paucity of fragility and vulnerability models, in particular in the developing world. this.
