The tubular bridge is designed as a steel truss structure. The truss construction method is a lightweight construction method and ideally suited to carrying large loads over large spans. In terms of load-bearing structure typology, the tubular bridges form bending and torsion-resistant truss tubes, which carry all vertical and horizontal loads to the supports. In order to ensure that the structure is fork-supported, the support points are each designed as a pair of supports. The position of the supports/bearing points of the bridges is selected in such a way that there are no restrictions on the use and operation of the buildings.
Between axis B5.13 - B5.16, the truss construction is designed as an oil tower with a height of around 23m for the storage of oil tanks. The support points of the bridges are designed as steel supports, which rest rigidly on a reinforced concrete base. The base serves as impact protection for the supports, but also offers advantages in terms of corrosion protection. To transfer the horizontal loads, the pairs of columns are stiffened with crossings. If the arrangement of a bracing is not possible for reasons of accessibility/use, the support structures are designed as portal frames. The columns are ultimately founded as shallow foundations in the form of strip foundations, which transfer the loads into the load-bearing subsoil.
