It’s an existing 6-span bridge with a total length of 168 m and a 10.40 to 13.90 m wide concrete slab deck. The pillars are 1.20 m circular concrete columns. We checked the type 2 rare SLS for the bridge to verify the interaction with the new CEVA railway station, which will be connected to the bridge walkway. A 3D modelling of frames and shells elements was carried out in SCIA Engineer. A global model has been built to calculate the strength, stiffness and displacements of the structure. Furthermore, dynamic calculations were made to analyse the seismic behaviour at the interface between both existing and new structures: movement amplitude and frequency. SCIA Engineer proved to be very flexible with input and output data. Maximum displacement amplitude was finely analysed to minimize expansion joint requirements.
