Vulnerability and Robustness of Civil Infrastructure Systems to Hurricanes
نویسندگان
چکیده
Civil infrastructure systems play an important role in community resilience. Without proper functioning of the infrastructure, especially power delivery, society will not recover quickly from disruptive events, such as hurricanes. In this paper, the vulnerability, response, and recovery of selected infrastructure at the system level for several hurricanes in the USA are modeled using geostatistical methods, employing post-event data. Inoperability is the main variable modeled for each infrastructure system. In this paper, robustness is a property considered to be the opposite of vulnerability, and it plays an important role in the resiliency modeling. The infrastructure systems examined in this paper are electric power delivery and telecommunications. Connections among the systems are briefly explored.

Extreme Events and the Sustainability of Civil Infrastructure Systems
The impact of extreme events is in reality the interaction among three systems; the natural environment, the human community, and the built environment the infrastructure that supports human activities. The sustainability of our infrastructure depends upon knowledge of the natural environment – for example, the research on global warming and its impact on meteorological events such as storms, d...
متن کاملProbabilistic Contaminant Source Identification in Water Distribution Infrastructure Systems
Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

متن کاملPrioritizing Resilience Enhancement Measures for Electric Distribution Networks Against Hurricanes
In recent years, climate change and increasing occurrence rate of high-impact rare (HR) natural events such as hurricanes have made it difficult to supply uninterrupted power to end-user customers. The extensive geographic area of electric distribution networks, as the last ring of the energy supply chain in power systems, has increased the vulnerability of these networks against natural events...
متن کاملEvaluation of Seismic Vulnerability of Reinforced Concrete Buildings Adjacent to the Deep Excavations
In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment and also changes in the propagation of seismic waves. This leads to permanent displacements in the foundation system. In this study, three RC building systems, i.e. 5, 10, ...
