The key features of the proposed methodology are the explicit definition of critical limit states (damage thresholds) for bridge components, considering the effects of geometry, material strength, reinforcement, and loading properties on the component capacity; the methodology also includes the correlation of local to global damage and the estimation of uncertainty in both capacity and demand. Advanced analysis methods and tools (nonlinear static and response history analysis, IDA) are used for bridge component capacity and demand estimation, whereas Latin Hypercube Sampling is used for uncertainty treatment. Based on processing of a large volume of results from analyses of full bridges, a simplified methodology is developed for seismic demand assessment, involving the use of an elastic (generic) bridge model and response spectrum analysis; demand is then related to component capacity and bridgespecific fragility curves are readily derived. The methodology can be applied, using an adhoc developed software, to a large number of bridges( having different geometries and properties) within a network, and direct and indirect losses can then be assessed.
