Triple Sports Hall in Passau, Germany

Customer Project

In Passau's Haidenhof district, a new sports hall extends to the existing school building. A 60 m long indoor athletics competition facility with four tracks, the so-called "running hose " , connects the hall with the existing building.

The real "eye-catcher" of this project are the roof members, which are castellated beams with longitudinal, sinusoidal openings.

The Dlubal customer Statik Breinbauer | Tragwerksingenieure performed the structural analysis of this new building. They utilized the finite element software RFEM.


The new hall was designed as a reinforced concrete skeleton structure. The hall roof is lightweight construction with a trapezoidal sheeting. The roof beams are IPE cross-sections with openings created in the central webs by curved flame cutting. The two wavy T-sections created were then offset by half the opening width and welded together again. The resulting cellular beam has a higher moment of inertia while utilizing the same amount of steel.

The running track on the upper floor also has a lightweight roof with transversal steel sections and a trapezoidal sheeting. The special feature of this bridge-like, 3D truss is the arrangement of the I-beams. They are arranged at 90° rotations and selected from either an HEAA, HEA or HEB beam of the same width.

Therefore, all connections points were welded directly to the flanges without additional gusset plates while maintaining an optimized design utilization. The floor structure includes HOLORIB composite concrete slabs which increased mass for vibration reduction and avoided any auxiliary supports during assembly.
