Triple Sports Hall in Passau, Germany
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 "sprint tunnel" , 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.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- I would like to perform a stability analysis of the upper flange in a long truss. What is the best way to proceed?
- Which cross-sections can I design with the "RF‑/STEEL Cold-Formed Sections" add-on module?
- What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?
- I perform a stability analysis of a beam for lateral-torsional buckling. Why is the modified reduction factor χLT,mod used in the design according to DIN EN 1993‑1‑1, 6.3.3 Method 2? Is it possible to deactivate this?
- I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
- I compare the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis including imperfections. The differences are very large. What is the reason?
- Is it possible to design member groups using the EC3 add-on module?
- Is it possible to use the RF‑/STEEL EC3 add-on module itself to specify the internal forces, for example, from another calculation or program?
- How can I set the required time t for the fire resistance design in RF‑/STEEL EC3?
- Why are the equivalent member designs grayed out in the Stability tab when activating the plastic designs by using the partial internal force method (RF‑/STEEL Plasticity)?
