Component

Significant life and property damage emerging from the occurrence of natural disasters including the recent earthquake in Haiti, the Tohoku earthquake and tsunami in Japan, as well as flooding and tornado activities in the central parts of the United States, has emphasized the significance of knowing the risks that natural hazards pose on the population and the infrastructure. Bridges are very important structural facilities in the road network system of any state, and this study will show and discuss ideas for the calculation of these risks, using the Florida bridges as a case study. The model used in the study incorporated statistical bridge data from the Department of Transportation, as well as historical data of natural disasters including hurricanes, tornadoes, earthquakes, wildfires, and flooding from the National Oceanic and Atmospheric Administration. The concept, analysis and model used the likelihood and consequence of natural disasters to evaluate the risk they pose on the Florida bridges. This model can be used by researchers and practitioner in greater depth for development of other models, including but not limited to the ranking of bridges for natural hazard mitigation, as well as the ranking of bridges for remediation acts after the occurrence of a natural disaster.
