Seismic reliability analysis of a gravity-designed twospan open-spandrel reinforced concrete arch bridge

This work deals with the seismic reliability analysis of an existing double-span open spandrel RC arch bridge, aiming to assess its seismic structural safety. In general, the seismic reliability analysis is a powerful tool able to combine seismic hazard and structural fragility for computing the probability of failure of a specific damage state of interest. The present work wants to apply this consolidated procedure to the specific case study of an open spandrel RC arch bridge located in Vicenza (IT), adopting as suitable engineering demand parameter the curvature ductiliy of the columns between the RC arches and the RC beams grillage.
