Field observations on concrete box girder railway bridges

Abstract

This paper presents the field observations performed during the static and dynamic tests of two concrete box girder railway bridges that are part of the railway line between Lisbon and Algarve, in the South of Portugal. After a brief description of the bridges, this paper presents the procedures used in the static and dynamic tests of both structures. The experimental results achieved are compared with the numerical values evaluated with a finite element model of each bridge.
