Quantitative and qualitative assessment of the seismic risk to highway bridges is crucial in
pre-earthquake planning, and post-earthquake response of transportation systems. Such …

Hurricane Katrina caused significant damage to the transportation system in the Gulf Coast
region. The overall cost to repair or replace the bridges damaged during the hurricane is …

As the use for regional seismic risk assessment increases, the need for reliable fragility
curves for portfolios (or classes) of structures becomes more important. Fragility curves for …

The lack of seismic design practices in the Central and Southeastern United States (Mid-
America), coupled with the potential for strong ground motion has led to a significant hazard …

Seismic induced pounding damage to bridge structures was repeatedly observed in many
previous major earthquakes. To avoid this adverse effect, extensive research efforts have …

Table 3.1–Idealization of bridge columns. 44 Table 4.1–Uncertainty distribution considered …

The central focus of this dissertation is a seismic vulnerability assessment of retrofitted
bridges. The objective of this work is to establish a methodology for the development of …

To avoid unseating of a deck, an adequate seat width must be provided. The seat width is
basically determined from maximum relative displacement between two bridge segments …

Considering the flexibility of isolation bearings, isolated bridges are susceptible to unseating
problems or even collapse due to excessive displacement under strong earthquakes. Shape …

Under strong ground excitations, highway bridges experience severe nonlinearity induced
by inelastic deformation at plastic hinges of piers and pounding between two adjacent …
