In this paper, an optimization approach is adopted to the performance-based seismic design of multi-column RC bridge piers exploiting the concept of quasi-isolation. A three-span continuous steel I-girder superstructure on multi-column pier substructures, typical of Illinois bridge configurations, is selected as a prototype for illustration.

Effects of the Seismic Input Variability on the Seismic Risk

Following the prescriptions of the Italian seismic code (D.M. 14.01.2008, herein called NTC08), there is the possibility for the engineers to employ real or artificial ground motions in the assessment of the nonlinear response of existing reinforced concrete (RC) structures. There are several databanks for downloading real accelerograms.

Application of a Probabilistic Mechanics-based Methodology

This study presents the evaluation of the seismic risk of the Italian multi-span simply supported and multi-span continuous RC bridges. The seismic fragility of the bridges is based on the computation of analytical fragility curves. A database is developed to collect the bridge information in terms of position, geometry and structural data.
