Abstract
This paper describes the dynamic and quasi-static tests performed in a multispan masonry arch bridge, under railway traffic actions. The dynamic forced vibration tests performed under train loading allowed to characterize the dynamic response of the bridge in terms of accelerations in the deck and piers. The quasi-static tests were performed using two in service freight train passages circulating at reduced speed and allowed monitoring particularly deformations in the arch. The main objective of this work is to use these experimental results for validation of the numerical model of Durrães bridge for dynamic and static analysis.
