| Abstract / Summary: |
Transportation and utility networks (e.g., water delivery, power, and oil systems)
are essential in the support of all economic and social activity of an industrialized region.
The functional loss of this critical urban infrastructure due to internal or external
perturbations, such as earthquakes, can severely impact commercial and industrial
activities on regional, national, and international scales, and on rapid and effective
emergency response and repair operations following the event. Therefore, understanding
the influence of hazards on these infrastructure systems and allocation of limited
resources for seismic retrofitting components of infrastructure systems are critical to
mitigate damage and to perform effective response and recovery efforts.
This study develops an approach for estimating seismic performance of complex
critical urban infrastructures and optimizing seismic retrofit of infrastructure systems
based on system-level performance under the constraint of finite resources. First, postearthquake
system performance of interdependent or independent infrastructure systems
is assessed based on a state-of-the-art network analysis model. Subsequently, a novel
optimization algorithm is developed to determine the best retrofit strategy to maximize
system performance with a limited budget. The developed methodology is applied to
substantial infrastructure systems for seismic loss estimation and mitigation study. The
resulting output of the methodology can provide useful insight to assist in prioritizing
components of infrastructure systems for seismic retrofit to enhance their post-earthquake
functionality. |
