Spencer, B.F., Jr. Kim, Young-Suk 2015-09-25T21:04:32Z 2015-09-25T21:04:32Z 10000-01-01 2007 2007 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 postearthquake functionality.
