Abstract:

The specific characteristics of near-field earthquake records can lead to different dynamic responses of bridges as compared to those of far-field ones. However, the effect of near-field strong ground motion has often been neglected in the seismic performance assessment of bridges. Curved bridges exhibit complicated responses in the course of an earthquake, due to their distinctive geometric status. Thereby in this study, the effect of curvature radius on the seismic damage probability of curved multi-frame concrete box-girder bridges was investigated. Bridge systems were modeled in OpenSEES software subjected to 80 near-fault ground-motion records, considering three components of the earthquake in three dimensions and including all the existent uncertainties. At the end, the fragility curves of the curved bridge were plotted.

Keywords:

Fragility curves, Seismic performance assessment, Curved bridges, OpenSEES
