Abstract (EN): This paper aims at presenting and discussing the strategies for updating the finite element numerical modeling of a stone masonry arch bridge using operational modal analysis. A 3D detailed numerical model is used to perform the bridge modal analysis and the bridge modal identification is based on in situ measurements recorded during ambient vibrations tests. The dynamic characteristics obtained through in situ measurements were estimated using analysis and signal processing software based on different techniques such as Peak Picking, Frequency Domain Decomposition (FDD and EFDD) and Stochastic Subspace Identification (SSI).
