All methods are complemented by advanced numerical simulations and a coarse to fine calibration strategy, based on the Douglas-Reid and the non-linear least squares approaches. Results obtained corroborate the robustness of the proposed approach, with an average relative error in frequencies of 1.2% and an average modal assurance criterion of 0.91. Considering this model, its current safety conditions were evaluated, obtaining a minimum safety factor of 2.1. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Geoinformática Arquitectura Historical bridge Reinforcement concrete Structural damage Terrestrial laser scanner Ambient vibration tests Finite element model updating Integrating geomatic approaches, Operational Modal Analysis, advanced numerical and updating methods to evaluate the current safety conditions of the historical Bôco Bridge info:eu-repo/semantics/article
