Next generation seismic fragility curves for california bridges incorporating the evolution in seismic design philosophy
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 assessments provide valuable knowledge about a number of principal effects of earthquakes such as traffic disruption of …

An investigation of the principles and practices of seismic isolation in bridge structures
Within the past decade, seismic isolation systems have gained rapid popularity in the earthquake resistant design of bridge structures. This popularity has come in response to the inadequacy of earlier seismic design and retrofit methodologies. The mechanical shortcomings and subsequent failure …

Nonlinear seismic analysis of quasi-isolation systems for earthquake protection of bridges
Quasi-isolation is a modern bridge seismic design philosophy where nonlinearity is permitted to occur in specific bearing components such that forces transferred into the substructure are reduced and isolation is achieved by sliding of the bearings. The system is a pragmatic approach for providing …

Ductility demands of filtered earthquakes on reinforced concrete frames
… demonstrated the destructive nature of seismic waves filtered through soft soils. Key characteristics of filtered ground motions are generally amplified acceleration, increased predominant period, and lengthened duration of strong shaking. Filtering of seismic waves through the soft …
