Integrated Approach for the Safety Evaluation of Masonry Bridges

EasyChair Preprint 13239

Abstract

Infrastructure is the backbone for the economic and social development of a territory, influencing its productivity, facilitating trade with other areas and markets, improving economic and social inclusion, and ensuring its environmental and climate sustainability. Italy has a rich and diverse asset of transport infrastructures. After the collapse of the Viadotto Polcevera in Genoa in 2018, the Italian Ministry of Infrastructure and Transportation enacted an important and extended plan for a common and unique safety management of bridges. In this scenario, masonry bridges represent a particular type of infrastructure due to their dated design and the employment of heterogenous materials. In this work, it is presented an integrated approach for the safety evaluation of masonry bridges which combines the use of Unmanned Aerial Vehicle (UAV) and on-site testing in the survey stage. The collected data is processed and employed with the Building Information Model (BIM) working methodology to define the three-dimensional model of the bridge. The BIM model is used to organize the collected information and set the finite element model of the bridge. Finally, nonlinear static analyses are adopted to evaluate the safety coefficients of the structure under traffic loads. The approach represents a comprehensive workflow to integrate modern technologies and methodologies as UAV, BIM, and nonlinear analysis to improve the safety evaluation of masonry infrastructures.
