Bridge fragilities to network fragilities in seismic scenarios: An integrated approach
Highlights Propose a methodology for reliability analysis of bridge networks under earthquakes. Evaluate the fragility of origin–destination paths in a hypothetic bridge network. Identify the importance of individual bridges in a network through a removal process. Suggest the seismic retrofit plan of a bridge network using bridges' importance.
Abstract As significant uncertainties are associated with the factors governing the operational characteristics of bridges following earthquakes, it is important to compute the reliability of transportation networks as a function of bridge fragility. A novel framework for the computation of transportation network fragilities following earthquakes is proposed herein, and the effectiveness of the proposed methodology is demonstrated using a hypothetical bridge network in California, USA. The proposed methodology affords the likelihood of functionality of bridge routes as a function of ground motion intensity. The network fragilities identified by this methodology can aid emergency responders and bridge owners in assessing the availability of possible routes after a seismic event based on the likelihoods of functionality of the routes.
