In the framework of the Veneto Regional Metropolitan Railway System, “Angel’s Hospital” railway station has been designed from scratch in Mestre (Venice, Italy). It is constituted of six distinguished independent areas. The main frame of each of them is made of curved I-section polycentric steel beams placed every 4m to support the secondary frame (purlines) and the cover mantle, which is made of aluminium ribbed double sheet sandwiches with a soundproof infill. A fire analysis (train fire) of the structure is carried out in an advanced calculation model, where the structure is modelled in a FEM program by beam elements. Localised fire model analysis with Eurocodes 1, 3 and 9 is performed taking into account time-and-space temperatures trends. Buckling stability analysis in fire condition is performed by varying Young modulus of structural elements in relation with the local induced temperature. |
