Summary

Belgian Railways intends to renovate and to extend the existing station in Mechelen, Belgium; comprising of 10 tracks. The extension consists of creating space underneath the railway infrastructure over a length of 190m, instead of the actual individual gates. In using continuous rails, an integral part of 190m without rail expansion joints is impossible. Therefore four main parts of 3 times 20m length in longitudinal direction and two parts in lateral directions will be used. Therefore a 3 dimensional, instead of a 2 dimensional approach, is needed. In having a continuous track on this structure the requirements of the UIC774-3 must be kept in mind, such as a maximum rail stress due to the combination effect of temperature, braking, acceleration, rotation of the deck ends. The combination of all these effects is studied in a finite integral 3D-element model containing the geometry of the structure with rails and roof structure. This paper will investigate the influence of the column rigidity in function of the rail stresses and structure displacements in order to obtain the best working solution used for the final design of the new station at Mechelen.
