Seismic Reliability Analysis: Application to an Existing Single-Span Open-Spandrel RC Arch Bridge

This work deals with the seismic reliability analysis of an existing single-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 the seismic hazard and the 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 inter-story drift ratio of the columns between the RC arches and the RC beams grillage.
