Seismic risk assessment of complex transportation networks
Abstract/Contents
- Abstract
- This dissertation focuses on understanding seismic risk and possible mitigation measures for complex transportation networks. It first introduces frameworks and computationally-feasible strategies for assessing probabilistic risk to these transportation networks, and applies them to a case study of the San Francisco Bay Area. Using these strategies for a set of earthquake events, values of a network-performance measure called "mode-destination accessibility" are then calculated to link physical infrastructure damage with the impact on people's ability to travel to desirable destinations, one measure of post-earthquake human welfare. As a result, at-risk communities are also identified. The results suggest that accessibility varies greatly between communities across the case study region, whereas the differences across income groups are more subtle. Furthermore, increased walkability of a region correlates with lower expected losses in accessibility. Finally, this dissertation contributes an automated framework incorporating seismic risk and network importance into bridge retrofit prioritization. A key finding is that bridges important for the network functionality after an earthquake are not necessarily the weakest bridges nor the bridges with the highest pre-earthquake traffic volume. Instead, bridges at moderately high seismic risk on non-redundant routes play a particularly critical role.
