Triple Sports Hall in Passau, Germany

In Passau's Haidenhof district, a new sports hall extends to the existing school building. A new 197-foot-long indoor running track with four lanes extends to the existing school building.

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

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

Structure

The new hall was designed as a reinforced concrete skeleton structure. The hall roof is of a 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 connection points were welded directly to the flanges without additional gusset plates while maintaining optimized design utilization. The floor structure includes HOLORIB composite concrete slabs, which increased the mass for vibration reduction and prevented the need for any temporary supports during assembly.
