| Zusammenfassung |
| In this study, a geographic information system (GIS)-based model was
developed to calculate the post-earthquake ignition probability of a
building, considering damage to the building's interior gas and electrical
distribution system and the overturning of appliances. In order to make our
model more reliable and realistic, a weighting factor was used to define the
possible existence of each appliance or other contents in the given
occupancy. A questionnaire was prepared to weigh the relevance of the
different components of post-earthquake ignitions using the analytical hierarchy
process (AHP). The questionnaire was evaluated by researchers who were
experienced in earthquake engineering and post-earthquake fires. The
developed model was implemented to HAZTURK's (Hazards Turkey) earthquake loss
assessment software, as developed by the Mid-America Earthquake Center with the
help of Istanbul Technical University. The developed post-earthquake
ignition tool was applied to Küçükçekmece, Istanbul, in
Turkey. The results were evaluated according to structure types, occupancy
types, the number of storeys, building codes and specified districts. The
evaluated results support the theory that post-earthquake ignition
probability is inversely proportional to the number of storeys and the
construction year, depending upon the building code. |
