Study of Dynamic and Static Response of an Old Truss Railroad Bridge
Publication: Earth and Space 2016: Engineering for Extreme Environments
ABSTRACT
The paper presents the response obtained from finite element model and field test of a railroad bridge under moving trains. The structure selected is the two-track through truss Devon Bridge in the busy Northeast Corridor at Milford, CT, U.S.A. Vertical displacement response, under various trains, along with the modal parameters (mode shapes and frequencies) of the bridge were obtained from FEM and field tests. The responses obtained from the FEM and field tests were compared and the FEM was refined. The result from this study is helpful in addressing the rising concerns over the safety of old steel truss railroad bridges, similar to the Devon Bridge, under moving passenger trains.
