'Angel’s Hospital' Railway Station In Mestre Venice: Fire Analysis

摘要

In the framework of the Veneto Regional Metropolitan Railway System, “Angel’s Hospital” railwaystation has been designed from scratch in Mestre (Venice, Italy). It is constituted of sixdistinguished independent areas. The main frame of each of them is made of curved I-sectionpolycentric steel beams placed every 4m to support the secondary frame (purlines) and the covermantle, 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 thestructure is modelled in a FEM program by beam elements. Localised fire model analysis withEurocodes 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 structuralelements in relation with the local induced temperature.
