The theoretical developments focus on a deeper The global analysis of the viaduct isĬarried out with special attention to the attributes that cause torque actionĪnd bending moment. The bridge is characterized by an axis curved in twoĭirections and a rectilinear segment. This paper presents the case study of anĮxisting viaduct built in North Italy, aiming to compare analytical approachesĪnd numerical modelling. However, they are still usefulįor the validation of FE models. With complex geometries and, therefore, the development of sophisticatedĪnalytical formulations is not needed anymore. Nowadays, the Finite Element Method (FEM) is a valid tool for the analysis of structures Or decks curved in the horizontal plane and subjected to out-of-plane loads. Implemented and exploited in the 1980s and 1990s for the design of bridge beams Various theories and analytical formulations were
