SEISMIC DAMAGE ASSESSMENT OF LIFELINES BASED ON GEOSPATIAL ANALYSIS
The main purpose of this study is to develop a Geospatial Information System (GIS) model with the ability to assess the seismic damage to lifelines for two well-known hazards, including ground shaking and ground failure simultaneously. The model that is developed and used in this study includes four main parts of database implementation, seismic hazard analysis, vulnerability assessment and seismic damage assessment to determine the lifeline’s damage probability. To consider uncertainty analysis in the model, Monte Carlo simulation is used based on 10,000 iterations. The results of hazard analysis indicated that peak ground acceleration is about 0.03 g to 0.3 g and there is slight to moderate damages to the desired infrastructure in the study area.
