Triple Sports Hall in Stuttgart-Waldau, Germany
The triple sports hall with a saw-tooth roof built in the German town of Stuttgart-Waldau impressively shows the sustainable perspectives of modern timber structures. The trusses arranged in the shape of boxes ensure optimal daylight.

Truss model data
Dlubal customer merz kley partner, situated in the Austrian town of Dornbirn, was responsible for the structural analysis and used RSTAB for it.
The new building, which opened in autumn 2020, comprises the hall including a gym with bleachers and several multifunction rooms, as well as an equipment room and changing rooms on one plane. An essential design element of the hall interior consists of ten trusses made of high-strength beech-laminated veneer lumber, which were connected in pairs, forming a spatial structural system. The utilization of this building material enables a low effective depth due to the cross-sections, which are as slender as possible. The sturdy boxes, having a span of about 1,181 inches, were clad with light-diffusing multi-wall polycarbonate sheets to ensure maximum daylight. With cladding on the sides and on the top using cross-laminated timber, these trusses weighing 22 tons each rest firmly on the columns, providing bracings for the structure without applying steel diagonals.
When prefabricating the trusses, self-drilling dowels were used and the assembly became easier and more precise due to a special setting tool. All other fasteners used in the rather hard timber had to be pre-drilled due to the high material density.

In this article, the adequacy of a 2x4 dimension lumber subject to combined bi-axial bending and axial compression is verified using RF-/TIMBER AWC add-on module. The beam-column properties and loading are based on example E1.8 of AWC Structural Wood Design Examples 2015/2018.
RF-/TIMBER AWC Add-on Module for RFEM/RSTAB | Design of Timber Members According to ANSI/AWC NDS-2015 (US Standard)
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
- Can I use RFEM to calculate a log house three-dimensionally?
- How do I display some results of all load cases in the printout report, but other results of selected load cases only?
- Can I design laminated veneer lumber with RFEM/RSTAB?
- I would like to carry out the flexural buckling design for timber components with imperfections and internal forces according to the second-order analysis. Is it sufficient to activate this in Details of the RF‑/TIMBER Pro add-on module or is it necessary to make additional settings?
- How can I model a timber-concrete composite floor?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The information about the limit time for the fire resistance design R in the RF‑TIMBER Pro add-on module is missing in the printout report. Is it possible to add this information to the printout report?
