ABSTRACT
ABSTRACT: Past experience showed too often that earthquake damage to highway components (e.g., bridges, roadways, tunnels, retaining walls, etc.) can severely disrupt traffic flows and thus negatively impacting on the economy of the region as well as post-earthquake emergency response and recovery. Furthermore, the extent of these impacts will depend not only on the nature and magnitude of the seismic damage sustained by the individual components, but also on the mode of functional impairment of the highway system as a network resulting from physical damage of its components. In order to estimate the effects of the earthquake on the performance of the transportation network, an analytical framework must be developed to integrate bridge and other structural performance model and transportation network model in the context of seismic risk assessment.
