The current AASHTO Specifications do not have adequate guidelines for seismic modeling and analysis of steel bridges. Bridge designers in seismic zones have always raised concerns about the adequacy of beam models in performing seismic analysis of steel bridges. This...

Run-to-run control using static linear models is examined. Conditions are presented for stability, (statistical) performance, and robustness using standard control theory. A simulation example shows the usefulness of the method applied to a rapid thermal oxidation...

Seismic retrofit of steel bridges requires more advanced analysis techniques to determine capacities and predict inelastic performance parameters. Normal engineering analysis practice assumes linear-elastic behavior for structural members, which fails to reliably...
