Abstract The paper presents the results obtained after a preliminary relief of a masonry bridge of the XIX century (1847-1849) made by mean of a series of photos by Unmanned Aerial Vehicles (UAV) technique useful to obtain a 3D Finite Element model of the bridge. Also, the information on the materials and structural details were obtained from a deep archival investigation to build a consistent numerical model of this historic bridge. The photos obtained by UAV technique then return an AutoCad model. The bridge is made of white limestone, it has three spans with barrel vaults on lowered arches, each about 3.50 m wide and a span length of about 7.90 m. The overall length of the bridge is equal to 35 m and 7.5 m high. The results will be useful for the preliminary numerical model for the subsequent tests campaign to investigate the dynamic characteristics of the bridge. The present research focuses on having identified a new methodology for exporting a simple model bridge that can also be applied to more complex historical buildings. © 2022 The Authors.

Introduction Among the types of construction that make up Italy's historical and architectural heritage, masonry arch bridges are of considerable interest, as they are still an essential part of today's communication infrastructure networks. Many of these ancient constructions, also due to the many changes they underwent over time, are constantly subject to potentially destructive actions due to traffic loads different from the ones they were designed to, large vibrations, foundation failures, high-risk natural events (earthquakes, river overflows or floods) and environmental degradation The paper presents the results obtained after a preliminary relief of a masonry bridge of the XIX century (1847-1849) made by i t i l i l t i l t t i i it l t l t i . l , t i ti t t i l t t l t il t i i l i ti ti t il i t t i l l t i i t i i . t t i t i t t t l. i i it li t , it t it l lt l , t . i l t t . . ll l t t i i l t . i . lt ill l t li i i l l t t t t i t i ti t t i t i ti t i . t i i ti i t l ti si l l i t t l li t l i t i l il i . t . li . .
