The residual structural performance of existing concrete bridges is investigated within the BRIDGE|50 research project. The activities include full-scale load tests on several prestressed concrete (PC) bridge deck beams sampled from a 50-year-old concrete viaduct recently dismantled in Italy. This paper presents the formulation of a PC beam finite element and the preliminary results of numerical simulations performed to reproduce the structural behavior of the first two tested beams. The purpose of the numerical investigation is to validate the nonlinear analysis model and support a proper planning of the future load tests.

Abstract

The residual structural performance of existing concrete bridges is investigated within the BRIDGE|50 research project. The activities include full-scale load tests on several prestressed concrete (PC) bridge deck beams sampled from a 50-year-old concrete viaduct recently dismantled in Italy. This paper presents the formulation of a PC beam finite element and the preliminary results of numerical simulations performed to reproduce the structural behavior of the first two tested beams. The purpose of the numerical investigation is to validate the nonlinear analysis model and support a proper planning of the future load tests.
