A kutatási téma leírása:
Recent earthquakes with high number of casualties and
enormous devastation proved that the hazard of natural disasters should not be neglected.
Preventive approaches have received greater attention recently. Research in earthquake
hazard mitigation has focused on evaluating possible damage scenarios for different
magnitude events. Two widely different approaches exist; one considers the effect of previous
earthquakes, listing the damaged buildings and casualties. The other offers a method to
evaluate possible damages prior to an event. The latter method facilitates prevention by
gathering information about the state of the building stock and the expected damages, so the
authorities can strengthen the most vulnerable buildings in order to mitigate risk.
The goals of the research are: to present the process of seismic risk evaluation of a town; to
integrate local site effects to previously determined seismic hazards; to examine the
vulnerability of the built environment considering the existing infrastructure elements; and
finally to combine the results and map risk scenarios to aid in the mitigation process.
Objectives can be: to refine the existing methods of visual inspection procedures and to
increase their reliability. Another task is to simplify the empirical methods in order to reduce
the working time required for the field survey. Another important aspect is the contribution of
local subsoil effects to earthquake risk, their magnitude and comparison with the procedure
proposed by EC8.
